Name: getyx
Synopsis:
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);
void getsyx(int y, int x);
int setsyx(int y, int x);
int getbegy(WINDOW *win);
int getbegx(WINDOW *win);
int getcury(WINDOW *win);
int getcurx(WINDOW *win);
int getpary(WINDOW *win);
int getparx(WINDOW *win);
int getmaxy(WINDOW *win);
int getmaxx(WINDOW *win);
Description:
The getyx() macro (defined in curses.h -- the prototypes here
are merely illustrative) puts the current cursor position of the
specified window into y and x. getbegyx() and getmaxyx() return
the starting coordinates and size of the specified window,
respectively. getparyx() returns the starting coordinates of the
parent's window, if the specified window is a subwindow;
otherwise it sets y and x to -1. These are all macros.
getsyx() gets the coordinates of the virtual screen cursor, and
stores them in y and x. If leaveok() is TRUE, it returns -1, -1.
If lines have been removed with ripoffline(), then getsyx()
includes these lines in its count; so, the returned y and x
values should only be used with setsyx().
setsyx() sets the virtual screen cursor to the y, x coordinates.
If y, x are -1, -1, leaveok() is set TRUE.
getsyx() and setsyx() are meant to be used by a library routine
that manipulates curses windows without altering the position of
the cursor. Note that getsyx() is defined only as a macro.
getbegy(), getbegx(), getcurx(), getcury(), getmaxy(),
getmaxx(), getpary(), and getparx() return the appropriate
coordinate or size values, or ERR in the case of a NULL window.
