+### 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);
+    void 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
+   either y or x is -1, leaveok() is set TRUE, else it's set FALSE.
+
+   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.
