Name
       touchwin - touch window

Syntax
       #include <cursesX.h>

       int touchwin(win)
       WINDOW *win;

Description
       This routine discards all optimization information for the specified window and assumes that the entire window has been drawn on.

       This  is  sometimes necessary when using overlapping windows, as a change to one window will affect the other window.  The records of which
       lines have been changed may not be correct for the window which has not been changed directly.

Return Values
       The function returns OK on success and ERR on error.
