.SH NAME
|
|
\fBgetyx\fR,
|
|
\fBgetparyx\fR,
|
|
\fBgetbegyx\fR,
|
|
\fBgetmaxyx\fR - get \fBcurses\fR cursor and window coordinates
|
|
.SH SYNOPSIS
|
|
\fB#include <curses.h>\fR
|
|
.sp
|
|
\fBvoid getyx(WINDOW *win, int y, int x);\fR
|
|
.br
|
|
\fBvoid getparyx(WINDOW *win, int y, int x);\fR
|
|
.br
|
|
\fBvoid getbegyx(WINDOW *win, int y, int x);\fR
|
|
.br
|
|
\fBvoid getmaxyx(WINDOW *win, int y, int x);\fR
|
|
.br
|
|
.SH DESCRIPTION
|
|
The \fBgetyx\fR macro places the current cursor position of the given window in
|
|
the two integer variables \fIy\fR and \fIx\fR.
|
|
.PP
|
|
If \fIwin\fR is a subwindow, the \fBgetparyx\fR macro places the beginning
|
|
coordinates of the subwindow relative to the parent window into two integer
|
|
variables \fIy\fR and \fIx\fR.
|
|
Otherwise, \fB-1\fR is placed into \fIy\fR and \fIx\fR.
|
|
.PP
|
|
Like \fBgetyx\fR, the \fBgetbegyx\fR and \fBgetmaxyx\fR macros store
|
|
the current beginning coordinates and size of the specified window.
|
|
.SH RETURN VALUE
|
|
The return values of these macros are undefined (i.e.,
|
|
they should not be used as the right-hand side of assignment statements).
|
|
.SH NOTES
|
|
All of these interfaces are macros.
|
|
A "\fB&\fR" is not necessary before the variables \fIy\fR and \fIx\fR.
|
|
.SH PORTABILITY
|
|
The
|
|
\fBgetyx\fR,
|
|
\fBgetparyx\fR,
|
|
\fBgetbegyx\fR and
|
|
\fBgetmaxyx\fR
|
|
macros are described in the XSI Curses standard, Issue 4.
|
|
.PP
|
|
This implementation also provides
|
|
\fBgetbegx\fR,
|
|
\fBgetbegy\fR,
|
|
\fBgetcurx\fR,
|
|
\fBgetcury\fR,
|
|
\fBgetmaxx\fR,
|
|
\fBgetmaxy\fR,
|
|
\fBgetparx\fR and
|
|
\fBgetpary\fR
|
|
for compatibility with older versions of curses.
|
|
X/Open does not define a corresponding \fBgetcuryx\fP function,
|
|
though that would be needed to make references to the WINDOW structure opaque.
