+
+  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.
