newwin.c
o __FULLINE added for AL/DL/CS optimization with __noqch.
refresh.c
o Attributes does not turned off before clearing screen, cause
highlighted screen.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
o make AL/DL/CS optimize not only for __FULLWIN but for __FULLLINE.
ATTENTION: original code works _only_for_ FULLWIN, i.e. if you
use two FULLLINE windows like in 'talk', you have full slow repaint with
original code, I enhance this thing. All other fixes marked
with phrase 'wrong for non-full windows' or WFNFW is continue of this fix.
I rewrite scroll code too for proper working (see below and tty.c
changes).
o DEBUG code always use 'i' index from 0 to curscr->maxy instead of
'i - win->begy', fixed
o check added into DEBUG to be shure that index inside current window.
o ->hash assigment code is WFNFW (forget win->begy).
o when CE usage required, and last spaces number counted, code don't check
attributes, so last standouted space will be incorrectly cleared.
o cep (start pointer) forget to add win->begy/win->begx, code WFNFW.
o clsp (last space) wrong in two places at once: forget to add win->begy
(WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer
arithmetics.
o clsp check incorrect: was 'clsp < win->maxx * __LDATASIZE', need to
be 'clsp < win->maxx
o Attributes does not turned off before clearing end of line, cause
highlighted end of line.
o When find how many lines from the top/bottom of the screen are unchanged,
code always forget '- win->begy', WFNFW.
o NO_JERKINESS code forgets to add win->begy, WFNFW.
o Curw & Curs changed in comment description
o In search for the largest block of text not changed forget to add
'- win->begy' (several places), WFNFW.
o Forget to add '- win->begy' for non-dirty lines, WFNFW.
o touchline forget to add '- win->begy', WFNFW.
o rewrite scrolln():
* remove win parameter, we deal with whole screen (curscr) now;
* use NL or '\n' instead of sf, it is faster in any case;
(imagine: cat written on curses now use '\n' for scroll
like standard cat, no ugly escapes)
* use dl (if present) instead of DL, if abs(n) == 1, the same
about al/sr, it is faster;
* change win->maxy to 'curscr->maxy - 1', we deal with whole screen
here, WFNFW.
* SF can be correctly issued only if cursor at bottom of scroll
region (whole screen region included too), fix this;
* sr/SR can be correctly issued only if cursor at top of scroll
region (whole screen region included too), fix this;
* use pre-calculaded (in setterm.c) __usecs variable to determine
usage of CS or AL/DL;
* completely rewrite scroll region stuff using __set_scroll_region
from tty.c (see below);
tty.c
o Added __set_scroll_region function which set CS region and stays
back in old position. Use SC/RC (save/restore cursor) if possible,
else use HO and __mvcur.
o __startwin: added __set_scroll_region(whole screen) at program
startup, if __usecs;
o endwin: added __set_scroll_region(whole screen) at program
exit, if __usecs;
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
setterm.c
o Add new variable __usecs, if (!AL/al || !Dl/dl) && CS && (SC && RC || HO)
(save/restore cursor used in __set_scroll_region in tty.c).
o Set __noqch, if !__usecs && (!AL/al || !DL/dl).
o Proper ospeed initialization for tputs, i.e. if speed == B9600,
ospeed = 13
curses.c
o Add __usecs variable that indicates usage of CS (if AL/DL absent).
curses.h
o Allow translation with applications which includes <sgtty.h>,
undef BXXX manually to avoid redefinition and include termios
to define proper ones.
o Define old-style names curx/begx/maxx/etc. for old applications.
Define _tty like __baset too.
o Typedef SGTTY type for old applications (SGTTY == struct termios).
o wstandout/wstandend should be int and not char*, some old
applications relay on this fact. See standout.c too.
o __FULLINE added indicated line width == terminal width, needed
for refresh using AL/DL/CS with __noqch, see refresh.c changes.
o Add extern __usecs variable that indicates usage of CS (if AL/DL absent).
o Add __set_scroll_region() prototype, see tty.c and refresh.c changes
for details.
o Change winch() character mask from 0177 to 0377, we don't need to
strip high bit on national characters.
o Allow translate on systems with _BSD_VA_LIST_ undefined, such as
FreeBSD 1.1.5.1
o __tty_fileno added to allows work with stdin redirected, see tty.c
o Privately declare tputs (..., void) and externally tputs(..., int),
many applications require this. Maybe not nice thing, but needed.
o Remove _putchar definition and replace it to proper _putchar
prototype, some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules. See putchar.c
cr_put.c
o __mvcur: if destline == destcol && outline == outcol do nothing,
i.e. don't issue any escapes.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
cur_hash.c
o Change char->unsigned char for proper sum 8-bit national characters.
getch.c
o check for inp == EOF added, don't add EOF to window.
getstr.c
o check for EOF added, don't add EOF to str.
insertln.c
o add cast to (int) in comparation of y and win->cury, this produce
big number (cast to (unsigned)) if y < 0
tstp.c
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
o add tstp() function for compatibility, some applications wants it.
standout.c
o Some old applications relay in fact that wstandout/wstandend
returns int instead of char*, change return type to OK/ERR.
putchar.c
o Add _putchar function (which calls __cputchar),
some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules.

newwin.c
o __FULLINE added for AL/DL/CS optimization with __noqch.
refresh.c
o Attributes does not turned off before clearing screen, cause
highlighted screen.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
o make AL/DL/CS optimize not only for __FULLWIN but for __FULLLINE.
ATTENTION: original code works _only_for_ FULLWIN, i.e. if you
use two FULLLINE windows like in 'talk', you have full slow repaint with
original code, I enhance this thing. All other fixes marked
with phrase 'wrong for non-full windows' or WFNFW is continue of this fix.
I rewrite scroll code too for proper working (see below and tty.c
changes).
o DEBUG code always use 'i' index from 0 to curscr->maxy instead of
'i - win->begy', fixed
o check added into DEBUG to be shure that index inside current window.
o ->hash assigment code is WFNFW (forget win->begy).
o when CE usage required, and last spaces number counted, code don't check
attributes, so last standouted space will be incorrectly cleared.
o cep (start pointer) forget to add win->begy/win->begx, code WFNFW.
o clsp (last space) wrong in two places at once: forget to add win->begy
(WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer
arithmetics.
o clsp check incorrect: was 'clsp < win->maxx * __LDATASIZE', need to
be 'clsp < win->maxx
o Attributes does not turned off before clearing end of line, cause
highlighted end of line.
o When find how many lines from the top/bottom of the screen are unchanged,
code always forget '- win->begy', WFNFW.
o NO_JERKINESS code forgets to add win->begy, WFNFW.
o Curw & Curs changed in comment description
o In search for the largest block of text not changed forget to add
'- win->begy' (several places), WFNFW.
o Forget to add '- win->begy' for non-dirty lines, WFNFW.
o touchline forget to add '- win->begy', WFNFW.
o rewrite scrolln():
* remove win parameter, we deal with whole screen (curscr) now;
* use NL or '\n' instead of sf, it is faster in any case;
(imagine: cat written on curses now use '\n' for scroll
like standard cat, no ugly escapes)
* use dl (if present) instead of DL, if abs(n) == 1, the same
about al/sr, it is faster;
* change win->maxy to 'curscr->maxy - 1', we deal with whole screen
here, WFNFW.
* SF can be correctly issued only if cursor at bottom of scroll
region (whole screen region included too), fix this;
* sr/SR can be correctly issued only if cursor at top of scroll
region (whole screen region included too), fix this;
* use pre-calculaded (in setterm.c) __usecs variable to determine
usage of CS or AL/DL;
* completely rewrite scroll region stuff using __set_scroll_region
from tty.c (see below);
tty.c
o Added __set_scroll_region function which set CS region and stays
back in old position. Use SC/RC (save/restore cursor) if possible,
else use HO and __mvcur.
o __startwin: added __set_scroll_region(whole screen) at program
startup, if __usecs;
o endwin: added __set_scroll_region(whole screen) at program
exit, if __usecs;
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
setterm.c
o Add new variable __usecs, if (!AL/al || !Dl/dl) && CS && (SC && RC || HO)
(save/restore cursor used in __set_scroll_region in tty.c).
o Set __noqch, if !__usecs && (!AL/al || !DL/dl).
o Proper ospeed initialization for tputs, i.e. if speed == B9600,
ospeed = 13
curses.c
o Add __usecs variable that indicates usage of CS (if AL/DL absent).
curses.h
o Allow translation with applications which includes <sgtty.h>,
undef BXXX manually to avoid redefinition and include termios
to define proper ones.
o Define old-style names curx/begx/maxx/etc. for old applications.
Define _tty like __baset too.
o Typedef SGTTY type for old applications (SGTTY == struct termios).
o wstandout/wstandend should be int and not char*, some old
applications relay on this fact. See standout.c too.
o __FULLINE added indicated line width == terminal width, needed
for refresh using AL/DL/CS with __noqch, see refresh.c changes.
o Add extern __usecs variable that indicates usage of CS (if AL/DL absent).
o Add __set_scroll_region() prototype, see tty.c and refresh.c changes
for details.
o Change winch() character mask from 0177 to 0377, we don't need to
strip high bit on national characters.
o Allow translate on systems with _BSD_VA_LIST_ undefined, such as
FreeBSD 1.1.5.1
o __tty_fileno added to allows work with stdin redirected, see tty.c
o Privately declare tputs (..., void) and externally tputs(..., int),
many applications require this. Maybe not nice thing, but needed.
o Remove _putchar definition and replace it to proper _putchar
prototype, some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules. See putchar.c
cr_put.c
o __mvcur: if destline == destcol && outline == outcol do nothing,
i.e. don't issue any escapes.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
cur_hash.c
o Change char->unsigned char for proper sum 8-bit national characters.
getch.c
o check for inp == EOF added, don't add EOF to window.

newwin.c
o __FULLINE added for AL/DL/CS optimization with __noqch.
refresh.c
o Attributes does not turned off before clearing screen, cause
highlighted screen.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
o make AL/DL/CS optimize not only for __FULLWIN but for __FULLLINE.
ATTENTION: original code works _only_for_ FULLWIN, i.e. if you
use two FULLLINE windows like in 'talk', you have full slow repaint with
original code, I enhance this thing. All other fixes marked
with phrase 'wrong for non-full windows' or WFNFW is continue of this fix.
I rewrite scroll code too for proper working (see below and tty.c
changes).
o DEBUG code always use 'i' index from 0 to curscr->maxy instead of
'i - win->begy', fixed
o check added into DEBUG to be shure that index inside current window.
o ->hash assigment code is WFNFW (forget win->begy).
o when CE usage required, and last spaces number counted, code don't check
attributes, so last standouted space will be incorrectly cleared.
o cep (start pointer) forget to add win->begy/win->begx, code WFNFW.
o clsp (last space) wrong in two places at once: forget to add win->begy
(WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer
arithmetics.
o clsp check incorrect: was 'clsp < win->maxx * __LDATASIZE', need to
be 'clsp < win->maxx
o Attributes does not turned off before clearing end of line, cause
highlighted end of line.
o When find how many lines from the top/bottom of the screen are unchanged,
code always forget '- win->begy', WFNFW.
o NO_JERKINESS code forgets to add win->begy, WFNFW.
o Curw & Curs changed in comment description
o In search for the largest block of text not changed forget to add
'- win->begy' (several places), WFNFW.
o Forget to add '- win->begy' for non-dirty lines, WFNFW.
o touchline forget to add '- win->begy', WFNFW.
o rewrite scrolln():
* remove win parameter, we deal with whole screen (curscr) now;
* use NL or '\n' instead of sf, it is faster in any case;
(imagine: cat written on curses now use '\n' for scroll
like standard cat, no ugly escapes)
* use dl (if present) instead of DL, if abs(n) == 1, the same
about al/sr, it is faster;
* change win->maxy to 'curscr->maxy - 1', we deal with whole screen
here, WFNFW.
* SF can be correctly issued only if cursor at bottom of scroll
region (whole screen region included too), fix this;
* sr/SR can be correctly issued only if cursor at top of scroll
region (whole screen region included too), fix this;
* use pre-calculaded (in setterm.c) __usecs variable to determine
usage of CS or AL/DL;
* completely rewrite scroll region stuff using __set_scroll_region
from tty.c (see below);
tty.c
o Added __set_scroll_region function which set CS region and stays
back in old position. Use SC/RC (save/restore cursor) if possible,
else use HO and __mvcur.
o __startwin: added __set_scroll_region(whole screen) at program
startup, if __usecs;
o endwin: added __set_scroll_region(whole screen) at program
exit, if __usecs;
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
setterm.c
o Add new variable __usecs, if (!AL/al || !Dl/dl) && CS && (SC && RC || HO)
(save/restore cursor used in __set_scroll_region in tty.c).
o Set __noqch, if !__usecs && (!AL/al || !DL/dl).
o Proper ospeed initialization for tputs, i.e. if speed == B9600,
ospeed = 13
curses.c
o Add __usecs variable that indicates usage of CS (if AL/DL absent).
curses.h
o Allow translation with applications which includes <sgtty.h>,
undef BXXX manually to avoid redefinition and include termios
to define proper ones.
o Define old-style names curx/begx/maxx/etc. for old applications.
Define _tty like __baset too.
o Typedef SGTTY type for old applications (SGTTY == struct termios).
o wstandout/wstandend should be int and not char*, some old
applications relay on this fact. See standout.c too.
o __FULLINE added indicated line width == terminal width, needed
for refresh using AL/DL/CS with __noqch, see refresh.c changes.
o Add extern __usecs variable that indicates usage of CS (if AL/DL absent).

* use dl (if present) instead of DL, if abs(n) == 1, the same
about al/sr, it is faster;
* change win->maxy to 'curscr->maxy - 1', we deal with whole screen
here, WFNFW.
* SF can be correctly issued only if cursor at bottom of scroll
region (whole screen region included too), fix this;
* sr/SR can be correctly issued only if cursor at top of scroll
region (whole screen region included too), fix this;
* use pre-calculaded (in setterm.c) __usecs variable to determine
usage of CS or AL/DL;
* completely rewrite scroll region stuff using __set_scroll_region
from tty.c (see below);
tty.c
o Added __set_scroll_region function which set CS region and stays
back in old position. Use SC/RC (save/restore cursor) if possible,
else use HO and __mvcur.
o __startwin: added __set_scroll_region(whole screen) at program
startup, if __usecs;
o endwin: added __set_scroll_region(whole screen) at program
exit, if __usecs;
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
setterm.c
o Add new variable __usecs, if (!AL/al || !Dl/dl) && CS && (SC && RC || HO)
(save/restore cursor used in __set_scroll_region in tty.c).
o Set __noqch, if !__usecs && (!AL/al || !DL/dl).
o Proper ospeed initialization for tputs, i.e. if speed == B9600,
ospeed = 13
curses.c
o Add __usecs variable that indicates usage of CS (if AL/DL absent).
curses.h
o Allow translation with applications which includes <sgtty.h>,
undef BXXX manually to avoid redefinition and include termios
to define proper ones.
o Define old-style names curx/begx/maxx/etc. for old applications.
Define _tty like __baset too.
o Typedef SGTTY type for old applications (SGTTY == struct termios).
o wstandout/wstandend should be int and not char*, some old
applications relay on this fact. See standout.c too.
o __FULLINE added indicated line width == terminal width, needed
for refresh using AL/DL/CS with __noqch, see refresh.c changes.
o Add extern __usecs variable that indicates usage of CS (if AL/DL absent).
o Add __set_scroll_region() prototype, see tty.c and refresh.c changes
for details.
o Change winch() character mask from 0177 to 0377, we don't need to
strip high bit on national characters.
o Allow translate on systems with _BSD_VA_LIST_ undefined, such as
FreeBSD 1.1.5.1
o __tty_fileno added to allows work with stdin redirected, see tty.c
o Privately declare tputs (..., void) and externally tputs(..., int),
many applications require this. Maybe not nice thing, but needed.
o Remove _putchar definition and replace it to proper _putchar
prototype, some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules. See putchar.c
cr_put.c
o __mvcur: if destline == destcol && outline == outcol do nothing,
i.e. don't issue any escapes.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
cur_hash.c
o Change char->unsigned char for proper sum 8-bit national characters.
getch.c
o check for inp == EOF added, don't add EOF to window.
getstr.c
o check for EOF added, don't add EOF to str.
insertln.c
o add cast to (int) in comparation of y and win->cury, this produce
big number (cast to (unsigned)) if y < 0
tstp.c
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
o add tstp() function for compatibility, some applications wants it.
standout.c
o Some old applications relay in fact that wstandout/wstandend
returns int instead of char*, change return type to OK/ERR.
putchar.c
o Add _putchar function (which calls __cputchar),
some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules.

newwin.c
o __FULLINE added for AL/DL/CS optimization with __noqch.
refresh.c
o Attributes does not turned off before clearing screen, cause
highlighted screen.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
o make AL/DL/CS optimize not only for __FULLWIN but for __FULLLINE.
ATTENTION: original code works _only_for_ FULLWIN, i.e. if you
use two FULLLINE windows like in 'talk', you have full slow repaint with
original code, I enhance this thing. All other fixes marked
with phrase 'wrong for non-full windows' or WFNFW is continue of this fix.
I rewrite scroll code too for proper working (see below and tty.c
changes).
o DEBUG code always use 'i' index from 0 to curscr->maxy instead of
'i - win->begy', fixed
o check added into DEBUG to be shure that index inside current window.
o ->hash assigment code is WFNFW (forget win->begy).
o when CE usage required, and last spaces number counted, code don't check
attributes, so last standouted space will be incorrectly cleared.
o cep (start pointer) forget to add win->begy/win->begx, code WFNFW.
o clsp (last space) wrong in two places at once: forget to add win->begy
(WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer
arithmetics.
o clsp check incorrect: was 'clsp < win->maxx * __LDATASIZE', need to
be 'clsp < win->maxx
o Attributes does not turned off before clearing end of line, cause
highlighted end of line.
o When find how many lines from the top/bottom of the screen are unchanged,
code always forget '- win->begy', WFNFW.
o NO_JERKINESS code forgets to add win->begy, WFNFW.
o Curw & Curs changed in comment description
o In search for the largest block of text not changed forget to add
'- win->begy' (several places), WFNFW.
o Forget to add '- win->begy' for non-dirty lines, WFNFW.
o touchline forget to add '- win->begy', WFNFW.
o rewrite scrolln():
* remove win parameter, we deal with whole screen (curscr) now;
* use NL or '\n' instead of sf, it is faster in any case;
(imagine: cat written on curses now use '\n' for scroll
like standard cat, no ugly escapes)

tty.c
o Added __set_scroll_region function which set CS region and stays
back in old position. Use SC/RC (save/restore cursor) if possible,
else use HO and __mvcur.
o __startwin: added __set_scroll_region(whole screen) at program
startup, if __usecs;
o endwin: added __set_scroll_region(whole screen) at program
exit, if __usecs;
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
setterm.c
o Add new variable __usecs, if (!AL/al || !Dl/dl) && CS && (SC && RC || HO)
(save/restore cursor used in __set_scroll_region in tty.c).
o Set __noqch, if !__usecs && (!AL/al || !DL/dl).
o Proper ospeed initialization for tputs, i.e. if speed == B9600,
ospeed = 13
curses.c
o Add __usecs variable that indicates usage of CS (if AL/DL absent).
curses.h
o Allow translation with applications which includes <sgtty.h>,
undef BXXX manually to avoid redefinition and include termios
to define proper ones.
o Define old-style names curx/begx/maxx/etc. for old applications.
Define _tty like __baset too.
o Typedef SGTTY type for old applications (SGTTY == struct termios).
o wstandout/wstandend should be int and not char*, some old
applications relay on this fact. See standout.c too.
o __FULLINE added indicated line width == terminal width, needed
for refresh using AL/DL/CS with __noqch, see refresh.c changes.
o Add extern __usecs variable that indicates usage of CS (if AL/DL absent).
o Add __set_scroll_region() prototype, see tty.c and refresh.c changes
for details.
o Change winch() character mask from 0177 to 0377, we don't need to
strip high bit on national characters.
o Allow translate on systems with _BSD_VA_LIST_ undefined, such as
FreeBSD 1.1.5.1
o __tty_fileno added to allows work with stdin redirected, see tty.c
o Privately declare tputs (..., void) and externally tputs(..., int),
many applications require this. Maybe not nice thing, but needed.
o Remove _putchar definition and replace it to proper _putchar
prototype, some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules. See putchar.c
cr_put.c
o __mvcur: if destline == destcol && outline == outcol do nothing,
i.e. don't issue any escapes.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
cur_hash.c
o Change char->unsigned char for proper sum 8-bit national characters.
getch.c
o check for inp == EOF added, don't add EOF to window.
getstr.c
o check for EOF added, don't add EOF to str.
insertln.c
o add cast to (int) in comparation of y and win->cury, this produce
big number (cast to (unsigned)) if y < 0
tstp.c
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
o add tstp() function for compatibility, some applications wants it.
standout.c
o Some old applications relay in fact that wstandout/wstandend
returns int instead of char*, change return type to OK/ERR.
putchar.c
o Add _putchar function (which calls __cputchar),
some old apps declares: 'extern int _putchar()'

newwin.c
o __FULLINE added for AL/DL/CS optimization with __noqch.
refresh.c
o Attributes does not turned off before clearing screen, cause
highlighted screen.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
o make AL/DL/CS optimize not only for __FULLWIN but for __FULLLINE.
ATTENTION: original code works _only_for_ FULLWIN, i.e. if you
use two FULLLINE windows like in 'talk', you have full slow repaint with
original code, I enhance this thing. All other fixes marked
with phrase 'wrong for non-full windows' or WFNFW is continue of this fix.
I rewrite scroll code too for proper working (see below and tty.c
changes).
o DEBUG code always use 'i' index from 0 to curscr->maxy instead of
'i - win->begy', fixed
o check added into DEBUG to be shure that index inside current window.
o ->hash assigment code is WFNFW (forget win->begy).
o when CE usage required, and last spaces number counted, code don't check
attributes, so last standouted space will be incorrectly cleared.
o cep (start pointer) forget to add win->begy/win->begx, code WFNFW.
o clsp (last space) wrong in two places at once: forget to add win->begy
(WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer
arithmetics.
o clsp check incorrect: was 'clsp < win->maxx * __LDATASIZE', need to
be 'clsp < win->maxx
o Attributes does not turned off before clearing end of line, cause
highlighted end of line.
o When find how many lines from the top/bottom of the screen are unchanged,
code always forget '- win->begy', WFNFW.
o NO_JERKINESS code forgets to add win->begy, WFNFW.
o Curw & Curs changed in comment description
o In search for the largest block of text not changed forget to add
'- win->begy' (several places), WFNFW.
o Forget to add '- win->begy' for non-dirty lines, WFNFW.
o touchline forget to add '- win->begy', WFNFW.
o rewrite scrolln():
* remove win parameter, we deal with whole screen (curscr) now;
* use NL or '\n' instead of sf, it is faster in any case;
(imagine: cat written on curses now use '\n' for scroll
like standard cat, no ugly escapes)
* use dl (if present) instead of DL, if abs(n) == 1, the same
about al/sr, it is faster;
* change win->maxy to 'curscr->maxy - 1', we deal with whole screen
here, WFNFW.
* SF can be correctly issued only if cursor at bottom of scroll
region (whole screen region included too), fix this;
* sr/SR can be correctly issued only if cursor at top of scroll
region (whole screen region included too), fix this;
* use pre-calculaded (in setterm.c) __usecs variable to determine
usage of CS or AL/DL;
* completely rewrite scroll region stuff using __set_scroll_region
from tty.c (see below);
tty.c
o Added __set_scroll_region function which set CS region and stays
back in old position. Use SC/RC (save/restore cursor) if possible,
else use HO and __mvcur.
o __startwin: added __set_scroll_region(whole screen) at program
startup, if __usecs;
o endwin: added __set_scroll_region(whole screen) at program
exit, if __usecs;
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
setterm.c
o Add new variable __usecs, if (!AL/al || !Dl/dl) && CS && (SC && RC || HO)
(save/restore cursor used in __set_scroll_region in tty.c).
o Set __noqch, if !__usecs && (!AL/al || !DL/dl).
o Proper ospeed initialization for tputs, i.e. if speed == B9600,
ospeed = 13
curses.c
o Add __usecs variable that indicates usage of CS (if AL/DL absent).
curses.h
o Allow translation with applications which includes <sgtty.h>,
undef BXXX manually to avoid redefinition and include termios
to define proper ones.
o Define old-style names curx/begx/maxx/etc. for old applications.
Define _tty like __baset too.
o Typedef SGTTY type for old applications (SGTTY == struct termios).
o wstandout/wstandend should be int and not char*, some old
applications relay on this fact. See standout.c too.
o __FULLINE added indicated line width == terminal width, needed

o __FULLINE added for AL/DL/CS optimization with __noqch.
refresh.c
o Attributes does not turned off before clearing screen, cause
highlighted screen.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
o make AL/DL/CS optimize not only for __FULLWIN but for __FULLLINE.
ATTENTION: original code works _only_for_ FULLWIN, i.e. if you
use two FULLLINE windows like in 'talk', you have full slow repaint with
original code, I enhance this thing. All other fixes marked
with phrase 'wrong for non-full windows' or WFNFW is continue of this fix.
I rewrite scroll code too for proper working (see below and tty.c
changes).
o DEBUG code always use 'i' index from 0 to curscr->maxy instead of
'i - win->begy', fixed
o check added into DEBUG to be shure that index inside current window.
o ->hash assigment code is WFNFW (forget win->begy).
o when CE usage required, and last spaces number counted, code don't check
attributes, so last standouted space will be incorrectly cleared.
o cep (start pointer) forget to add win->begy/win->begx, code WFNFW.
o clsp (last space) wrong in two places at once: forget to add win->begy
(WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer
arithmetics.
o clsp check incorrect: was 'clsp < win->maxx * __LDATASIZE', need to
be 'clsp < win->maxx
o Attributes does not turned off before clearing end of line, cause
highlighted end of line.
o When find how many lines from the top/bottom of the screen are unchanged,
code always forget '- win->begy', WFNFW.
o NO_JERKINESS code forgets to add win->begy, WFNFW.
o Curw & Curs changed in comment description
o In search for the largest block of text not changed forget to add
'- win->begy' (several places), WFNFW.
o Forget to add '- win->begy' for non-dirty lines, WFNFW.
o touchline forget to add '- win->begy', WFNFW.
o rewrite scrolln():
* remove win parameter, we deal with whole screen (curscr) now;
* use NL or '\n' instead of sf, it is faster in any case;
(imagine: cat written on curses now use '\n' for scroll
like standard cat, no ugly escapes)
* use dl (if present) instead of DL, if abs(n) == 1, the same
about al/sr, it is faster;
* change win->maxy to 'curscr->maxy - 1', we deal with whole screen
here, WFNFW.
* SF can be correctly issued only if cursor at bottom of scroll
region (whole screen region included too), fix this;
* sr/SR can be correctly issued only if cursor at top of scroll
region (whole screen region included too), fix this;
* use pre-calculaded (in setterm.c) __usecs variable to determine
usage of CS or AL/DL;
* completely rewrite scroll region stuff using __set_scroll_region
from tty.c (see below);
tty.c
o Added __set_scroll_region function which set CS region and stays
back in old position. Use SC/RC (save/restore cursor) if possible,
else use HO and __mvcur.
o __startwin: added __set_scroll_region(whole screen) at program
startup, if __usecs;
o endwin: added __set_scroll_region(whole screen) at program
exit, if __usecs;
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
setterm.c
o Add new variable __usecs, if (!AL/al || !Dl/dl) && CS && (SC && RC || HO)
(save/restore cursor used in __set_scroll_region in tty.c).
o Set __noqch, if !__usecs && (!AL/al || !DL/dl).
o Proper ospeed initialization for tputs, i.e. if speed == B9600,
ospeed = 13
curses.c
o Add __usecs variable that indicates usage of CS (if AL/DL absent).
curses.h
o Allow translation with applications which includes <sgtty.h>,
undef BXXX manually to avoid redefinition and include termios
to define proper ones.
o Define old-style names curx/begx/maxx/etc. for old applications.
Define _tty like __baset too.
o Typedef SGTTY type for old applications (SGTTY == struct termios).
o wstandout/wstandend should be int and not char*, some old
applications relay on this fact. See standout.c too.
o __FULLINE added indicated line width == terminal width, needed
for refresh using AL/DL/CS with __noqch, see refresh.c changes.
o Add extern __usecs variable that indicates usage of CS (if AL/DL absent).
o Add __set_scroll_region() prototype, see tty.c and refresh.c changes

newwin.c
o __FULLINE added for AL/DL/CS optimization with __noqch.
refresh.c
o Attributes does not turned off before clearing screen, cause
highlighted screen.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
o make AL/DL/CS optimize not only for __FULLWIN but for __FULLLINE.
ATTENTION: original code works _only_for_ FULLWIN, i.e. if you
use two FULLLINE windows like in 'talk', you have full slow repaint with
original code, I enhance this thing. All other fixes marked
with phrase 'wrong for non-full windows' or WFNFW is continue of this fix.
I rewrite scroll code too for proper working (see below and tty.c
changes).
o DEBUG code always use 'i' index from 0 to curscr->maxy instead of
'i - win->begy', fixed
o check added into DEBUG to be shure that index inside current window.
o ->hash assigment code is WFNFW (forget win->begy).
o when CE usage required, and last spaces number counted, code don't check
attributes, so last standouted space will be incorrectly cleared.
o cep (start pointer) forget to add win->begy/win->begx, code WFNFW.
o clsp (last space) wrong in two places at once: forget to add win->begy
(WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer
arithmetics.
o clsp check incorrect: was 'clsp < win->maxx * __LDATASIZE', need to
be 'clsp < win->maxx
o Attributes does not turned off before clearing end of line, cause
highlighted end of line.
o When find how many lines from the top/bottom of the screen are unchanged,
code always forget '- win->begy', WFNFW.
o NO_JERKINESS code forgets to add win->begy, WFNFW.
o Curw & Curs changed in comment description
o In search for the largest block of text not changed forget to add
'- win->begy' (several places), WFNFW.
o Forget to add '- win->begy' for non-dirty lines, WFNFW.
o touchline forget to add '- win->begy', WFNFW.
o rewrite scrolln():
* remove win parameter, we deal with whole screen (curscr) now;
* use NL or '\n' instead of sf, it is faster in any case;
(imagine: cat written on curses now use '\n' for scroll
like standard cat, no ugly escapes)
* use dl (if present) instead of DL, if abs(n) == 1, the same
about al/sr, it is faster;
* change win->maxy to 'curscr->maxy - 1', we deal with whole screen
here, WFNFW.
* SF can be correctly issued only if cursor at bottom of scroll
region (whole screen region included too), fix this;
* sr/SR can be correctly issued only if cursor at top of scroll
region (whole screen region included too), fix this;
* use pre-calculaded (in setterm.c) __usecs variable to determine
usage of CS or AL/DL;
* completely rewrite scroll region stuff using __set_scroll_region
from tty.c (see below);
tty.c
o Added __set_scroll_region function which set CS region and stays
back in old position. Use SC/RC (save/restore cursor) if possible,
else use HO and __mvcur.
o __startwin: added __set_scroll_region(whole screen) at program
startup, if __usecs;

o Set __noqch, if !__usecs && (!AL/al || !DL/dl).
o Proper ospeed initialization for tputs, i.e. if speed == B9600,
ospeed = 13
curses.c
o Add __usecs variable that indicates usage of CS (if AL/DL absent).
curses.h
o Allow translation with applications which includes <sgtty.h>,

applications relay on this fact. See standout.c too.
o __FULLINE added indicated line width == terminal width, needed
for refresh using AL/DL/CS with __noqch, see refresh.c changes.
o Add extern __usecs variable that indicates usage of CS (if AL/DL absent).
o Add __set_scroll_region() prototype, see tty.c and refresh.c changes
for details.
o Change winch() character mask from 0177 to 0377, we don't need to
strip high bit on national characters.
o Allow translate on systems with _BSD_VA_LIST_ undefined, such as
FreeBSD 1.1.5.1
o __tty_fileno added to allows work with stdin redirected, see tty.c
o Privately declare tputs (..., void) and externally tputs(..., int),
many applications require this. Maybe not nice thing, but needed.
o Remove _putchar definition and replace it to proper _putchar
prototype, some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules. See putchar.c
cr_put.c
o __mvcur: if destline == destcol && outline == outcol do nothing,
i.e. don't issue any escapes.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
cur_hash.c
o Change char->unsigned char for proper sum 8-bit national characters.
getch.c
o check for inp == EOF added, don't add EOF to window.
getstr.c
o check for EOF added, don't add EOF to str.
insertln.c
o add cast to (int) in comparation of y and win->cury, this produce
big number (cast to (unsigned)) if y < 0
tstp.c
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
o add tstp() function for compatibility, some applications wants it.
standout.c
o Some old applications relay in fact that wstandout/wstandend
returns int instead of char*, change return type to OK/ERR.
putchar.c
o Add _putchar function (which calls __cputchar),
some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules.

newwin.c
o __FULLINE added for AL/DL/CS optimization with __noqch.
refresh.c
o Attributes does not turned off before clearing screen, cause
highlighted screen.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
o make AL/DL/CS optimize not only for __FULLWIN but for __FULLLINE.
ATTENTION: original code works _only_for_ FULLWIN, i.e. if you
use two FULLLINE windows like in 'talk', you have full slow repaint with
original code, I enhance this thing. All other fixes marked
with phrase 'wrong for non-full windows' or WFNFW is continue of this fix.
I rewrite scroll code too for proper working (see below and tty.c
changes).
o DEBUG code always use 'i' index from 0 to curscr->maxy instead of
'i - win->begy', fixed
o check added into DEBUG to be shure that index inside current window.
o ->hash assigment code is WFNFW (forget win->begy).
o when CE usage required, and last spaces number counted, code don't check
attributes, so last standouted space will be incorrectly cleared.
o cep (start pointer) forget to add win->begy/win->begx, code WFNFW.
o clsp (last space) wrong in two places at once: forget to add win->begy
(WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer
arithmetics.
o clsp check incorrect: was 'clsp < win->maxx * __LDATASIZE', need to
be 'clsp < win->maxx
o Attributes does not turned off before clearing end of line, cause
highlighted end of line.
o When find how many lines from the top/bottom of the screen are unchanged,
code always forget '- win->begy', WFNFW.
o NO_JERKINESS code forgets to add win->begy, WFNFW.
o Curw & Curs changed in comment description
o In search for the largest block of text not changed forget to add
'- win->begy' (several places), WFNFW.
o Forget to add '- win->begy' for non-dirty lines, WFNFW.
o touchline forget to add '- win->begy', WFNFW.
o rewrite scrolln():
* remove win parameter, we deal with whole screen (curscr) now;
* use NL or '\n' instead of sf, it is faster in any case;
(imagine: cat written on curses now use '\n' for scroll
like standard cat, no ugly escapes)
* use dl (if present) instead of DL, if abs(n) == 1, the same
about al/sr, it is faster;
* change win->maxy to 'curscr->maxy - 1', we deal with whole screen
here, WFNFW.
* SF can be correctly issued only if cursor at bottom of scroll
region (whole screen region included too), fix this;
* sr/SR can be correctly issued only if cursor at top of scroll
region (whole screen region included too), fix this;
* use pre-calculaded (in setterm.c) __usecs variable to determine
usage of CS or AL/DL;
* completely rewrite scroll region stuff using __set_scroll_region
from tty.c (see below);
tty.c
o Added __set_scroll_region function which set CS region and stays
back in old position. Use SC/RC (save/restore cursor) if possible,
else use HO and __mvcur.
o __startwin: added __set_scroll_region(whole screen) at program
startup, if __usecs;
o endwin: added __set_scroll_region(whole screen) at program
exit, if __usecs;
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
setterm.c
o Add new variable __usecs, if (!AL/al || !Dl/dl) && CS && (SC && RC || HO)
(save/restore cursor used in __set_scroll_region in tty.c).
o Set __noqch, if !__usecs && (!AL/al || !DL/dl).
o Proper ospeed initialization for tputs, i.e. if speed == B9600,
ospeed = 13
curses.c
o Add __usecs variable that indicates usage of CS (if AL/DL absent).
curses.h
o Allow translation with applications which includes <sgtty.h>,
undef BXXX manually to avoid redefinition and include termios
to define proper ones.
o Define old-style names curx/begx/maxx/etc. for old applications.
Define _tty like __baset too.
o Typedef SGTTY type for old applications (SGTTY == struct termios).

|
|
* There are 2 major issues here that make this rotation non-trivial:
|
|
|
|
|
* 1. Scrolling in a scrolling region bounded by the top
|
|
|
|
|
* and bottom regions determined (whose size is sc_region).
|
|
|
|
|
* 2. As a result of the use of the mod function, there may be a
|
|
|
|
|
* period introduced, i.e., 2 maps to 4, 4 to 6, n-2 to 0, and
|
|
|
|
|
* 0 to 2, which then causes all odd lines not to be rotated.
|
|
|
|
|
* To remedy this, an index of the end ( = beginning) of the
|
|
|
|
|
* current 'period' is kept, cur_period, and when it is reached,
|
|
|
|
|
* the next period is started from cur_period + 1 which is
|
|
|
|
|
* guaranteed not to have been reached since that would mean that
|
|
|
|
|
* all records would have been reached. (think about it...).
|
|
|
|
|
*
|
|
|
|
|
* Lines in the rotation can have 3 attributes which are marked on the
|
|
|
|
|
* line so that curscr is consistent with the visual screen.
|
|
|
|
|
* 1. Not dirty -- lines inside the scrolled block, top region or
|
|
|
|
|
* bottom region.
|
|
|
|
|
* 2. Blank lines -- lines in the differential of the scrolling
|
|
|
|
|
* region adjacent to top and bot regions
|
|
|
|
|
* depending on scrolling direction.
|
|
|
|
|
* 3. Dirty line -- all other lines are marked dirty.

newwin.c
o __FULLINE added for AL/DL/CS optimization with __noqch.
refresh.c
o Attributes does not turned off before clearing screen, cause
highlighted screen.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
o make AL/DL/CS optimize not only for __FULLWIN but for __FULLLINE.
ATTENTION: original code works _only_for_ FULLWIN, i.e. if you
use two FULLLINE windows like in 'talk', you have full slow repaint with
original code, I enhance this thing. All other fixes marked
with phrase 'wrong for non-full windows' or WFNFW is continue of this fix.
I rewrite scroll code too for proper working (see below and tty.c
changes).
o DEBUG code always use 'i' index from 0 to curscr->maxy instead of
'i - win->begy', fixed
o check added into DEBUG to be shure that index inside current window.
o ->hash assigment code is WFNFW (forget win->begy).
o when CE usage required, and last spaces number counted, code don't check
attributes, so last standouted space will be incorrectly cleared.
o cep (start pointer) forget to add win->begy/win->begx, code WFNFW.
o clsp (last space) wrong in two places at once: forget to add win->begy
(WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer
arithmetics.
o clsp check incorrect: was 'clsp < win->maxx * __LDATASIZE', need to
be 'clsp < win->maxx
o Attributes does not turned off before clearing end of line, cause
highlighted end of line.
o When find how many lines from the top/bottom of the screen are unchanged,
code always forget '- win->begy', WFNFW.
o NO_JERKINESS code forgets to add win->begy, WFNFW.
o Curw & Curs changed in comment description
o In search for the largest block of text not changed forget to add
'- win->begy' (several places), WFNFW.
o Forget to add '- win->begy' for non-dirty lines, WFNFW.
o touchline forget to add '- win->begy', WFNFW.
o rewrite scrolln():
* remove win parameter, we deal with whole screen (curscr) now;
* use NL or '\n' instead of sf, it is faster in any case;
(imagine: cat written on curses now use '\n' for scroll
like standard cat, no ugly escapes)
* use dl (if present) instead of DL, if abs(n) == 1, the same
about al/sr, it is faster;
* change win->maxy to 'curscr->maxy - 1', we deal with whole screen
here, WFNFW.
* SF can be correctly issued only if cursor at bottom of scroll
region (whole screen region included too), fix this;
* sr/SR can be correctly issued only if cursor at top of scroll
region (whole screen region included too), fix this;
* use pre-calculaded (in setterm.c) __usecs variable to determine
usage of CS or AL/DL;
* completely rewrite scroll region stuff using __set_scroll_region
from tty.c (see below);
tty.c
o Added __set_scroll_region function which set CS region and stays
back in old position. Use SC/RC (save/restore cursor) if possible,
else use HO and __mvcur.
o __startwin: added __set_scroll_region(whole screen) at program
startup, if __usecs;
o endwin: added __set_scroll_region(whole screen) at program
exit, if __usecs;
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
setterm.c
o Add new variable __usecs, if (!AL/al || !Dl/dl) && CS && (SC && RC || HO)
(save/restore cursor used in __set_scroll_region in tty.c).
o Set __noqch, if !__usecs && (!AL/al || !DL/dl).
o Proper ospeed initialization for tputs, i.e. if speed == B9600,
ospeed = 13
curses.c
o Add __usecs variable that indicates usage of CS (if AL/DL absent).
curses.h
o Allow translation with applications which includes <sgtty.h>,
undef BXXX manually to avoid redefinition and include termios
to define proper ones.
o Define old-style names curx/begx/maxx/etc. for old applications.
Define _tty like __baset too.
o Typedef SGTTY type for old applications (SGTTY == struct termios).
o wstandout/wstandend should be int and not char*, some old
applications relay on this fact. See standout.c too.
o __FULLINE added indicated line width == terminal width, needed
for refresh using AL/DL/CS with __noqch, see refresh.c changes.
o Add extern __usecs variable that indicates usage of CS (if AL/DL absent).
o Add __set_scroll_region() prototype, see tty.c and refresh.c changes
for details.
o Change winch() character mask from 0177 to 0377, we don't need to
strip high bit on national characters.
o Allow translate on systems with _BSD_VA_LIST_ undefined, such as
FreeBSD 1.1.5.1
o __tty_fileno added to allows work with stdin redirected, see tty.c
o Privately declare tputs (..., void) and externally tputs(..., int),
many applications require this. Maybe not nice thing, but needed.
o Remove _putchar definition and replace it to proper _putchar
prototype, some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules. See putchar.c
cr_put.c
o __mvcur: if destline == destcol && outline == outcol do nothing,
i.e. don't issue any escapes.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
cur_hash.c
o Change char->unsigned char for proper sum 8-bit national characters.
getch.c
o check for inp == EOF added, don't add EOF to window.
getstr.c
o check for EOF added, don't add EOF to str.
insertln.c
o add cast to (int) in comparation of y and win->cury, this produce
big number (cast to (unsigned)) if y < 0
tstp.c
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
o add tstp() function for compatibility, some applications wants it.
standout.c
o Some old applications relay in fact that wstandout/wstandend
returns int instead of char*, change return type to OK/ERR.
putchar.c
o Add _putchar function (which calls __cputchar),
some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules.

back in old position. Use SC/RC (save/restore cursor) if possible,
else use HO and __mvcur.
o __startwin: added __set_scroll_region(whole screen) at program
startup, if __usecs;
o endwin: added __set_scroll_region(whole screen) at program
exit, if __usecs;
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
setterm.c
o Add new variable __usecs, if (!AL/al || !Dl/dl) && CS && (SC && RC || HO)
(save/restore cursor used in __set_scroll_region in tty.c).
o Set __noqch, if !__usecs && (!AL/al || !DL/dl).
o Proper ospeed initialization for tputs, i.e. if speed == B9600,
ospeed = 13
curses.c
o Add __usecs variable that indicates usage of CS (if AL/DL absent).
curses.h
o Allow translation with applications which includes <sgtty.h>,
undef BXXX manually to avoid redefinition and include termios
to define proper ones.
o Define old-style names curx/begx/maxx/etc. for old applications.
Define _tty like __baset too.
o Typedef SGTTY type for old applications (SGTTY == struct termios).
o wstandout/wstandend should be int and not char*, some old
applications relay on this fact. See standout.c too.
o __FULLINE added indicated line width == terminal width, needed
for refresh using AL/DL/CS with __noqch, see refresh.c changes.
o Add extern __usecs variable that indicates usage of CS (if AL/DL absent).
o Add __set_scroll_region() prototype, see tty.c and refresh.c changes
for details.
o Change winch() character mask from 0177 to 0377, we don't need to
strip high bit on national characters.
o Allow translate on systems with _BSD_VA_LIST_ undefined, such as
FreeBSD 1.1.5.1
o __tty_fileno added to allows work with stdin redirected, see tty.c
o Privately declare tputs (..., void) and externally tputs(..., int),
many applications require this. Maybe not nice thing, but needed.
o Remove _putchar definition and replace it to proper _putchar
prototype, some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules. See putchar.c
cr_put.c
o __mvcur: if destline == destcol && outline == outcol do nothing,
i.e. don't issue any escapes.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
cur_hash.c
o Change char->unsigned char for proper sum 8-bit national characters.
getch.c
o check for inp == EOF added, don't add EOF to window.
getstr.c
o check for EOF added, don't add EOF to str.
insertln.c
o add cast to (int) in comparation of y and win->cury, this produce
big number (cast to (unsigned)) if y < 0
tstp.c
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
o add tstp() function for compatibility, some applications wants it.
standout.c
o Some old applications relay in fact that wstandout/wstandend
returns int instead of char*, change return type to OK/ERR.
putchar.c
o Add _putchar function (which calls __cputchar),
some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules.

o __FULLINE added for AL/DL/CS optimization with __noqch.
refresh.c
o Attributes does not turned off before clearing screen, cause
highlighted screen.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
o make AL/DL/CS optimize not only for __FULLWIN but for __FULLLINE.
ATTENTION: original code works _only_for_ FULLWIN, i.e. if you
use two FULLLINE windows like in 'talk', you have full slow repaint with
original code, I enhance this thing. All other fixes marked
with phrase 'wrong for non-full windows' or WFNFW is continue of this fix.
I rewrite scroll code too for proper working (see below and tty.c
changes).
o DEBUG code always use 'i' index from 0 to curscr->maxy instead of
'i - win->begy', fixed
o check added into DEBUG to be shure that index inside current window.
o ->hash assigment code is WFNFW (forget win->begy).
o when CE usage required, and last spaces number counted, code don't check
attributes, so last standouted space will be incorrectly cleared.
o cep (start pointer) forget to add win->begy/win->begx, code WFNFW.
o clsp (last space) wrong in two places at once: forget to add win->begy
(WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer
arithmetics.
o clsp check incorrect: was 'clsp < win->maxx * __LDATASIZE', need to
be 'clsp < win->maxx
o Attributes does not turned off before clearing end of line, cause
highlighted end of line.
o When find how many lines from the top/bottom of the screen are unchanged,
code always forget '- win->begy', WFNFW.
o NO_JERKINESS code forgets to add win->begy, WFNFW.
o Curw & Curs changed in comment description
o In search for the largest block of text not changed forget to add
'- win->begy' (several places), WFNFW.
o Forget to add '- win->begy' for non-dirty lines, WFNFW.
o touchline forget to add '- win->begy', WFNFW.
o rewrite scrolln():
* remove win parameter, we deal with whole screen (curscr) now;
* use NL or '\n' instead of sf, it is faster in any case;
(imagine: cat written on curses now use '\n' for scroll
like standard cat, no ugly escapes)
* use dl (if present) instead of DL, if abs(n) == 1, the same
about al/sr, it is faster;
* change win->maxy to 'curscr->maxy - 1', we deal with whole screen
here, WFNFW.
* SF can be correctly issued only if cursor at bottom of scroll
region (whole screen region included too), fix this;
* sr/SR can be correctly issued only if cursor at top of scroll
region (whole screen region included too), fix this;
* use pre-calculaded (in setterm.c) __usecs variable to determine
usage of CS or AL/DL;
* completely rewrite scroll region stuff using __set_scroll_region

(WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer
arithmetics.
o clsp check incorrect: was 'clsp < win->maxx * __LDATASIZE', need to
be 'clsp < win->maxx
o Attributes does not turned off before clearing end of line, cause
highlighted end of line.
o When find how many lines from the top/bottom of the screen are unchanged,
code always forget '- win->begy', WFNFW.
o NO_JERKINESS code forgets to add win->begy, WFNFW.
o Curw & Curs changed in comment description
o In search for the largest block of text not changed forget to add
'- win->begy' (several places), WFNFW.
o Forget to add '- win->begy' for non-dirty lines, WFNFW.
o touchline forget to add '- win->begy', WFNFW.
o rewrite scrolln():
* remove win parameter, we deal with whole screen (curscr) now;
* use NL or '\n' instead of sf, it is faster in any case;
(imagine: cat written on curses now use '\n' for scroll
like standard cat, no ugly escapes)
* use dl (if present) instead of DL, if abs(n) == 1, the same
about al/sr, it is faster;
* change win->maxy to 'curscr->maxy - 1', we deal with whole screen
here, WFNFW.
* SF can be correctly issued only if cursor at bottom of scroll
region (whole screen region included too), fix this;
* sr/SR can be correctly issued only if cursor at top of scroll
region (whole screen region included too), fix this;
* use pre-calculaded (in setterm.c) __usecs variable to determine
usage of CS or AL/DL;
* completely rewrite scroll region stuff using __set_scroll_region
from tty.c (see below);
tty.c
o Added __set_scroll_region function which set CS region and stays
back in old position. Use SC/RC (save/restore cursor) if possible,
else use HO and __mvcur.
o __startwin: added __set_scroll_region(whole screen) at program
startup, if __usecs;
o endwin: added __set_scroll_region(whole screen) at program
exit, if __usecs;
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
setterm.c
o Add new variable __usecs, if (!AL/al || !Dl/dl) && CS && (SC && RC || HO)
(save/restore cursor used in __set_scroll_region in tty.c).
o Set __noqch, if !__usecs && (!AL/al || !DL/dl).
o Proper ospeed initialization for tputs, i.e. if speed == B9600,
ospeed = 13
curses.c
o Add __usecs variable that indicates usage of CS (if AL/DL absent).
curses.h
o Allow translation with applications which includes <sgtty.h>,
undef BXXX manually to avoid redefinition and include termios
to define proper ones.
o Define old-style names curx/begx/maxx/etc. for old applications.
Define _tty like __baset too.
o Typedef SGTTY type for old applications (SGTTY == struct termios).
o wstandout/wstandend should be int and not char*, some old
applications relay on this fact. See standout.c too.
o __FULLINE added indicated line width == terminal width, needed
for refresh using AL/DL/CS with __noqch, see refresh.c changes.
o Add extern __usecs variable that indicates usage of CS (if AL/DL absent).
o Add __set_scroll_region() prototype, see tty.c and refresh.c changes
for details.
o Change winch() character mask from 0177 to 0377, we don't need to
strip high bit on national characters.
o Allow translate on systems with _BSD_VA_LIST_ undefined, such as
FreeBSD 1.1.5.1
o __tty_fileno added to allows work with stdin redirected, see tty.c
o Privately declare tputs (..., void) and externally tputs(..., int),
many applications require this. Maybe not nice thing, but needed.
o Remove _putchar definition and replace it to proper _putchar
prototype, some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules. See putchar.c
cr_put.c
o __mvcur: if destline == destcol && outline == outcol do nothing,
i.e. don't issue any escapes.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
cur_hash.c
o Change char->unsigned char for proper sum 8-bit national characters.
getch.c
o check for inp == EOF added, don't add EOF to window.
getstr.c
o check for EOF added, don't add EOF to str.
insertln.c
o add cast to (int) in comparation of y and win->cury, this produce
big number (cast to (unsigned)) if y < 0
tstp.c
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
o add tstp() function for compatibility, some applications wants it.
standout.c
o Some old applications relay in fact that wstandout/wstandend
returns int instead of char*, change return type to OK/ERR.
putchar.c
o Add _putchar function (which calls __cputchar),
some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules.

newwin.c
o __FULLINE added for AL/DL/CS optimization with __noqch.
refresh.c
o Attributes does not turned off before clearing screen, cause
highlighted screen.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
o make AL/DL/CS optimize not only for __FULLWIN but for __FULLLINE.
ATTENTION: original code works _only_for_ FULLWIN, i.e. if you
use two FULLLINE windows like in 'talk', you have full slow repaint with
original code, I enhance this thing. All other fixes marked
with phrase 'wrong for non-full windows' or WFNFW is continue of this fix.
I rewrite scroll code too for proper working (see below and tty.c
changes).
o DEBUG code always use 'i' index from 0 to curscr->maxy instead of
'i - win->begy', fixed
o check added into DEBUG to be shure that index inside current window.
o ->hash assigment code is WFNFW (forget win->begy).
o when CE usage required, and last spaces number counted, code don't check
attributes, so last standouted space will be incorrectly cleared.
o cep (start pointer) forget to add win->begy/win->begx, code WFNFW.
o clsp (last space) wrong in two places at once: forget to add win->begy
(WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer

newwin.c
o __FULLINE added for AL/DL/CS optimization with __noqch.
refresh.c
o Attributes does not turned off before clearing screen, cause
highlighted screen.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
o make AL/DL/CS optimize not only for __FULLWIN but for __FULLLINE.
ATTENTION: original code works _only_for_ FULLWIN, i.e. if you
use two FULLLINE windows like in 'talk', you have full slow repaint with
original code, I enhance this thing. All other fixes marked
with phrase 'wrong for non-full windows' or WFNFW is continue of this fix.
I rewrite scroll code too for proper working (see below and tty.c
changes).
o DEBUG code always use 'i' index from 0 to curscr->maxy instead of
'i - win->begy', fixed
o check added into DEBUG to be shure that index inside current window.
o ->hash assigment code is WFNFW (forget win->begy).
o when CE usage required, and last spaces number counted, code don't check
attributes, so last standouted space will be incorrectly cleared.
o cep (start pointer) forget to add win->begy/win->begx, code WFNFW.
o clsp (last space) wrong in two places at once: forget to add win->begy
(WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer
arithmetics.
o clsp check incorrect: was 'clsp < win->maxx * __LDATASIZE', need to
be 'clsp < win->maxx
o Attributes does not turned off before clearing end of line, cause
highlighted end of line.
o When find how many lines from the top/bottom of the screen are unchanged,
code always forget '- win->begy', WFNFW.
o NO_JERKINESS code forgets to add win->begy, WFNFW.
o Curw & Curs changed in comment description
o In search for the largest block of text not changed forget to add
'- win->begy' (several places), WFNFW.
o Forget to add '- win->begy' for non-dirty lines, WFNFW.
o touchline forget to add '- win->begy', WFNFW.
o rewrite scrolln():
* remove win parameter, we deal with whole screen (curscr) now;
* use NL or '\n' instead of sf, it is faster in any case;
(imagine: cat written on curses now use '\n' for scroll
like standard cat, no ugly escapes)
* use dl (if present) instead of DL, if abs(n) == 1, the same
about al/sr, it is faster;
* change win->maxy to 'curscr->maxy - 1', we deal with whole screen
here, WFNFW.
* SF can be correctly issued only if cursor at bottom of scroll
region (whole screen region included too), fix this;
* sr/SR can be correctly issued only if cursor at top of scroll
region (whole screen region included too), fix this;
* use pre-calculaded (in setterm.c) __usecs variable to determine
usage of CS or AL/DL;
* completely rewrite scroll region stuff using __set_scroll_region
from tty.c (see below);
tty.c
o Added __set_scroll_region function which set CS region and stays
back in old position. Use SC/RC (save/restore cursor) if possible,
else use HO and __mvcur.
o __startwin: added __set_scroll_region(whole screen) at program
startup, if __usecs;
o endwin: added __set_scroll_region(whole screen) at program
exit, if __usecs;
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
setterm.c
o Add new variable __usecs, if (!AL/al || !Dl/dl) && CS && (SC && RC || HO)
(save/restore cursor used in __set_scroll_region in tty.c).
o Set __noqch, if !__usecs && (!AL/al || !DL/dl).
o Proper ospeed initialization for tputs, i.e. if speed == B9600,
ospeed = 13
curses.c
o Add __usecs variable that indicates usage of CS (if AL/DL absent).
curses.h
o Allow translation with applications which includes <sgtty.h>,
undef BXXX manually to avoid redefinition and include termios
to define proper ones.
o Define old-style names curx/begx/maxx/etc. for old applications.
Define _tty like __baset too.
o Typedef SGTTY type for old applications (SGTTY == struct termios).
o wstandout/wstandend should be int and not char*, some old
applications relay on this fact. See standout.c too.
o __FULLINE added indicated line width == terminal width, needed
for refresh using AL/DL/CS with __noqch, see refresh.c changes.
o Add extern __usecs variable that indicates usage of CS (if AL/DL absent).
o Add __set_scroll_region() prototype, see tty.c and refresh.c changes
for details.
o Change winch() character mask from 0177 to 0377, we don't need to
strip high bit on national characters.
o Allow translate on systems with _BSD_VA_LIST_ undefined, such as
FreeBSD 1.1.5.1
o __tty_fileno added to allows work with stdin redirected, see tty.c
o Privately declare tputs (..., void) and externally tputs(..., int),
many applications require this. Maybe not nice thing, but needed.
o Remove _putchar definition and replace it to proper _putchar
prototype, some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules. See putchar.c
cr_put.c
o __mvcur: if destline == destcol && outline == outcol do nothing,
i.e. don't issue any escapes.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
cur_hash.c
o Change char->unsigned char for proper sum 8-bit national characters.
getch.c
o check for inp == EOF added, don't add EOF to window.

newwin.c
o __FULLINE added for AL/DL/CS optimization with __noqch.
refresh.c
o Attributes does not turned off before clearing screen, cause
highlighted screen.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
o make AL/DL/CS optimize not only for __FULLWIN but for __FULLLINE.
ATTENTION: original code works _only_for_ FULLWIN, i.e. if you
use two FULLLINE windows like in 'talk', you have full slow repaint with
original code, I enhance this thing. All other fixes marked
with phrase 'wrong for non-full windows' or WFNFW is continue of this fix.
I rewrite scroll code too for proper working (see below and tty.c
changes).
o DEBUG code always use 'i' index from 0 to curscr->maxy instead of
'i - win->begy', fixed
o check added into DEBUG to be shure that index inside current window.
o ->hash assigment code is WFNFW (forget win->begy).
o when CE usage required, and last spaces number counted, code don't check
attributes, so last standouted space will be incorrectly cleared.
o cep (start pointer) forget to add win->begy/win->begx, code WFNFW.
o clsp (last space) wrong in two places at once: forget to add win->begy
(WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer
arithmetics.
o clsp check incorrect: was 'clsp < win->maxx * __LDATASIZE', need to
be 'clsp < win->maxx
o Attributes does not turned off before clearing end of line, cause
highlighted end of line.
o When find how many lines from the top/bottom of the screen are unchanged,
code always forget '- win->begy', WFNFW.
o NO_JERKINESS code forgets to add win->begy, WFNFW.
o Curw & Curs changed in comment description
o In search for the largest block of text not changed forget to add
'- win->begy' (several places), WFNFW.
o Forget to add '- win->begy' for non-dirty lines, WFNFW.
o touchline forget to add '- win->begy', WFNFW.
o rewrite scrolln():
* remove win parameter, we deal with whole screen (curscr) now;
* use NL or '\n' instead of sf, it is faster in any case;
(imagine: cat written on curses now use '\n' for scroll
like standard cat, no ugly escapes)
* use dl (if present) instead of DL, if abs(n) == 1, the same
about al/sr, it is faster;
* change win->maxy to 'curscr->maxy - 1', we deal with whole screen
here, WFNFW.
* SF can be correctly issued only if cursor at bottom of scroll
region (whole screen region included too), fix this;
* sr/SR can be correctly issued only if cursor at top of scroll
region (whole screen region included too), fix this;
* use pre-calculaded (in setterm.c) __usecs variable to determine
usage of CS or AL/DL;
* completely rewrite scroll region stuff using __set_scroll_region
from tty.c (see below);
tty.c
o Added __set_scroll_region function which set CS region and stays
back in old position. Use SC/RC (save/restore cursor) if possible,
else use HO and __mvcur.

o Forget to add '- win->begy' for non-dirty lines, WFNFW.
o touchline forget to add '- win->begy', WFNFW.
o rewrite scrolln():
* remove win parameter, we deal with whole screen (curscr) now;
* use NL or '\n' instead of sf, it is faster in any case;
(imagine: cat written on curses now use '\n' for scroll
like standard cat, no ugly escapes)
* use dl (if present) instead of DL, if abs(n) == 1, the same
about al/sr, it is faster;
* change win->maxy to 'curscr->maxy - 1', we deal with whole screen
here, WFNFW.
* SF can be correctly issued only if cursor at bottom of scroll
region (whole screen region included too), fix this;
* sr/SR can be correctly issued only if cursor at top of scroll
region (whole screen region included too), fix this;
* use pre-calculaded (in setterm.c) __usecs variable to determine
usage of CS or AL/DL;
* completely rewrite scroll region stuff using __set_scroll_region
from tty.c (see below);
tty.c
o Added __set_scroll_region function which set CS region and stays
back in old position. Use SC/RC (save/restore cursor) if possible,
else use HO and __mvcur.
o __startwin: added __set_scroll_region(whole screen) at program
startup, if __usecs;
o endwin: added __set_scroll_region(whole screen) at program
exit, if __usecs;
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
setterm.c
o Add new variable __usecs, if (!AL/al || !Dl/dl) && CS && (SC && RC || HO)
(save/restore cursor used in __set_scroll_region in tty.c).
o Set __noqch, if !__usecs && (!AL/al || !DL/dl).
o Proper ospeed initialization for tputs, i.e. if speed == B9600,
ospeed = 13
curses.c
o Add __usecs variable that indicates usage of CS (if AL/DL absent).
curses.h
o Allow translation with applications which includes <sgtty.h>,
undef BXXX manually to avoid redefinition and include termios
to define proper ones.
o Define old-style names curx/begx/maxx/etc. for old applications.
Define _tty like __baset too.
o Typedef SGTTY type for old applications (SGTTY == struct termios).
o wstandout/wstandend should be int and not char*, some old
applications relay on this fact. See standout.c too.
o __FULLINE added indicated line width == terminal width, needed
for refresh using AL/DL/CS with __noqch, see refresh.c changes.
o Add extern __usecs variable that indicates usage of CS (if AL/DL absent).
o Add __set_scroll_region() prototype, see tty.c and refresh.c changes
for details.
o Change winch() character mask from 0177 to 0377, we don't need to
strip high bit on national characters.
o Allow translate on systems with _BSD_VA_LIST_ undefined, such as
FreeBSD 1.1.5.1
o __tty_fileno added to allows work with stdin redirected, see tty.c
o Privately declare tputs (..., void) and externally tputs(..., int),
many applications require this. Maybe not nice thing, but needed.
o Remove _putchar definition and replace it to proper _putchar
prototype, some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules. See putchar.c
cr_put.c
o __mvcur: if destline == destcol && outline == outcol do nothing,
i.e. don't issue any escapes.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
cur_hash.c
o Change char->unsigned char for proper sum 8-bit national characters.
getch.c
o check for inp == EOF added, don't add EOF to window.
getstr.c
o check for EOF added, don't add EOF to str.
insertln.c
o add cast to (int) in comparation of y and win->cury, this produce
big number (cast to (unsigned)) if y < 0
tstp.c
o Fix all tc{set/get}attrs to works properly, when stdin redirected,
use /dev/tty in this case (needed for some applications).
o add tstp() function for compatibility, some applications wants it.
standout.c
o Some old applications relay in fact that wstandout/wstandend
returns int instead of char*, change return type to OK/ERR.
putchar.c
o Add _putchar function (which calls __cputchar),
some old apps declares: 'extern int _putchar()'
and don't even include curses.h in such modules.

newwin.c
o __FULLINE added for AL/DL/CS optimization with __noqch.
refresh.c
o Attributes does not turned off before clearing screen, cause
highlighted screen.
o Proper usage of 'affcnt' tputs parameter, affects terminals with
padding.
o make AL/DL/CS optimize not only for __FULLWIN but for __FULLLINE.
ATTENTION: original code works _only_for_ FULLWIN, i.e. if you
use two FULLLINE windows like in 'talk', you have full slow repaint with
original code, I enhance this thing. All other fixes marked
with phrase 'wrong for non-full windows' or WFNFW is continue of this fix.
I rewrite scroll code too for proper working (see below and tty.c
changes).
o DEBUG code always use 'i' index from 0 to curscr->maxy instead of
'i - win->begy', fixed
o check added into DEBUG to be shure that index inside current window.
o ->hash assigment code is WFNFW (forget win->begy).
o when CE usage required, and last spaces number counted, code don't check
attributes, so last standouted space will be incorrectly cleared.
o cep (start pointer) forget to add win->begy/win->begx, code WFNFW.
o clsp (last space) wrong in two places at once: forget to add win->begy
(WFNFW) and incorrectly use 'win->begx * __LDATASIZE' in pointer
arithmetics.
o clsp check incorrect: was 'clsp < win->maxx * __LDATASIZE', need to
be 'clsp < win->maxx
o Attributes does not turned off before clearing end of line, cause
highlighted end of line.
o When find how many lines from the top/bottom of the screen are unchanged,
code always forget '- win->begy', WFNFW.
o NO_JERKINESS code forgets to add win->begy, WFNFW.
o Curw & Curs changed in comment description
o In search for the largest block of text not changed forget to add
'- win->begy' (several places), WFNFW.
