.SH NAME
|
|
\fBinch\fR,
|
|
\fBwinch\fR,
|
|
\fBmvinch\fR,
|
|
\fBmvwinch\fR \- get a character and attributes from a \fBcurses\fR window
|
|
.SH SYNOPSIS
|
|
\fB#include <curses.h>\fR
|
|
.sp
|
|
\fBchtype inch(void);\fR
|
|
.br
|
|
\fBchtype winch(WINDOW *win);\fR
|
|
.br
|
|
\fBchtype mvinch(int y, int x);\fR
|
|
.br
|
|
\fBchtype mvwinch(WINDOW *win, int y, int x);\fR
|
|
.br
|
|
.SH DESCRIPTION
|
|
These routines return the character, of type \fBchtype\fR, at the current
|
|
position in the named window. If any attributes are set for that position,
|
|
their values are OR'ed into the value returned. Constants defined in
|
|
\fB<curses.h>\fR can be used with the \fB&\fR (logical AND) operator to
|
|
extract the character or attributes alone.
|
|
.
|
|
.SS Attributes
|
|
The following bit-masks may be AND-ed with characters returned by \fBwinch\fR.
|
|

|
|
.TS
|
|
l l .
|
|
\fBA_CHARTEXT\fR Bit-mask to extract character
|
|
\fBA_ATTRIBUTES\fR Bit-mask to extract attributes
|
|
\fBA_COLOR\fR Bit-mask to extract color-pair field information
|
|
.TE
|
|
.SH RETURN VALUE
|
|
Functions with a "mv" prefix first perform a cursor movement using
|
|
\fBwmove\fP, and return an error if the position is outside the window,
|
|
or if the window pointer is null.
|
|
.SH NOTES
|
|
Note that all of these routines may be macros.
|
|
.SH PORTABILITY
|
|
These functions are described in the XSI Curses standard, Issue 4.
|
|
.SH SEE ALSO

described in
