.SH DESCRIPTION
|
|
The \fBunctrl\fR macro expands to a character string which is a printable
|
|
representation of the character \fIc\fR. Control characters are displayed in
|
|
the \fB^\fR\fIX\fR notation. Printing characters are displayed as is.
|
|
|
|
The \fBkeyname\fR routine returns a character string corresponding to
|
|
the key \fIc\fR.
|
|
|
|
The \fBfilter\fR routine, if used, must be called before \fBinitscr\fR or
|
|
\fBnewterm\fR are called. The effect is that, during those calls, \fBLINES\fR
|
|
is set to 1; the capabilities \fBclear\fR, \fBcup\fR, \fBcud\fR, \fBcud1\fR,
|
|
\fBcuu1\fR, \fBcuu\fR, \fBvpa\fR are disabled; and the \fBhome\fR string is
|
|
set to the value of \fBcr\fR.
|
|
|
|
The \fBuse_env\fR routine, if used, is called before \fBinitscr\fR or
|
|
\fBnewterm\fR are called. When called with \fBFALSE\fR as an
|
|
argument, the values of \fBlines\fR and \fBcolumns\fR specified in the
|
|
\fIterminfo\fR database will be used, even if environment variables
|
|
\fBLINES\fR and \fBCOLUMNS\fR (used by default) are set, or if
|
|
\fBcurses\fR is running in a window (in which case default behavior
|
|
would be to use the window size if \fBLINES\fR and \fBCOLUMNS\fR are
|
|
not set).
|
|
|
|
The \fBputwin\fR routine writes all data associated with window \fIwin\fR into
|
|
the file to which \fIfilep\fR points. This information can be later retrieved
|
|
using the \fBgetwin\fR function.
|
|
|
|
The \fBgetwin\fR routine reads window related data stored in the file by
|
|
\fBputwin\fR. The routine then creates and initializes a new window using that
|
|
data. It returns a pointer to the new window.
|
|
|
|
The \fBdelay_output\fR routine inserts an \fIms\fR millisecond pause
|
|
in output. This routine should not be used extensively because
|
|
padding characters are used rather than a CPU pause.
|
|
|
|
The \fBflushinp\fR routine throws away any typeahead that has been typed by the
|
|
user and has not yet been read by the program.
|
|
.SH RETURN VALUE
|
|
Except for \fBflushinp\fR, routines that return an integer return \fBERR\fR
|
|
upon failure and \fBOK\fR (SVr4 specifies only "an integer value other than
|
|
\fBERR\fR") upon successful completion.
|
|
|
|
\fBflushinp\fR always returns \fBOK\fR.
|
|
|
|
Routines that return pointers return \fBNULL\fR on error.
|
|
.SH PORTABILITY
|
|
The XSI Curses standard, Issue 4 describes these functions.
|
|
|
|
The SVr4 documentation describes the action of \fBfilter\fR only in the vaguest
|
|
terms. The description here is adapted from the XSI Curses standard (which
|
|
erroneously fails to describe the disabling of \fBcuu\fR).
|
|
.SH NOTES
|
|
Note that \fBunctrl\fR is a macro, which is defined in <\fBunctrl.h\fR>.
|
|
