.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.
