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 touchwin function returns OK on success and ERR on error.
