timeout, wtimeout 

The timeout and wtimeout routines are used to set a timed blocking or
nonblocking read for a window.

Syntax 

     #include <curses.h>

     int timeout(int delay);
     int wtimeout(WINDOW win, int delay);

Parameters 

delay                 The number of milliseconds to block or wait for
                      input.

win                   A pointer to the window in which to set the timed
                      blocking.

Return Values 

OK                    Successful completion.

ERR                   An error occurred.

Description 

The timeout() and wtimeout() routines set the length of time getch()
waits for input for windows stdscr and win, respectively.  These routines
are similar to nodelay except the time to block or wait for input can be
specified.

A negative delay causes the program to wait indefinitely for input; a
delay of 0 returns ERR if no input is ready; and a positive delay blocks
until input arrives or the time specified expires (in which case, ERR is
returned).


NOTE  The timeout() routine is a macro.
