curs_getyx: getyx, getparyx, getbegyx, getmaxyx -- get curses cursor and window coordinates

Synopsis

cc [flag . . .] file -locurses [library . . .]

#include <ocurses.h>

void getyx(WINDOW win, int y, int x);
void getparyx(WINDOW win, int y, int x);
void getbegyx(WINDOW win, int y, int x);
void getmaxyx(WINDOW win, int y, int x);

Description

With the getyx macro, the cursor position of the window is placed in the two integer variables y and x.

With the getparyx macro, if win is a subwindow, the beginning coordinates of the subwindow relative to the parent window are placed into two integer variables, y and x. Otherwise, -1 is placed into y and x.

Like getyx, the getbegyx and getmaxyx macros store the current beginning coordinates and size of the specified window.

Return values

The return values of these macros are undefined (that is, they should not be used as the right-hand side of assignment statements).

Notices

The header file ocurses.h automatically includes the header files stdio.h and unctrl.h.

Note that all of these interfaces are macros and that ``&'' is not necessary before the variables y and x.
