+.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 functions
+\fBgetbegx\fR,
+\fBgetbegy\fR,
+\fBgetcurx\fR,
+\fBgetcury\fR,
+\fBgetmaxx\fR,
+\fBgetmaxy\fR,
+\fBgetparx\fR and
+\fBgetpary\fR
+for compatibility with older versions of curses.
+.PP
+Although X/Open Curses does not address this,
+many implementations provide members of the WINDOW structure
+containing values corresponding to these macros.
+For best portability, do not rely on using the data in WINDOW,
+since some implementations make WINDOW opaque (do not allow
+direct use of its members).
+.PP
+Besides the problem of opaque structures,
+the data stored in like-named members may not have like-values in
+different implementations.
+For example, the WINDOW._maxx and WINDOW._maxy values in ncurses
+have (at least since release 1.8.1) differed by one from some
+other implementations.
+The difference is hidden by means of the macro \fBgetmaxyx\fP.
