SYNOPSIS

cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib \
-R /usr/xpg4/lib -lcurses [ library... ]

c89 [ flag... ] file... -lcurses [ library... ]

#include <curses.h>

int halfdelay(int tenths);

DESCRIPTION

The halfdelay() function is similar to cbreak(3XCURSES) in that when
set, characters typed by the user are immediately processed by the
program. The difference is that ERR is returned if no input is
received after tenths tenths seconds.


The nocbreak(3XCURSES) function should be used to leave half-delay
mode.

PARAMETERS

tenths
Is the number of tenths of seconds for which to block input
(1 to 255).

RETURN VALUES

On success, the halfdelay() function returns OK. Otherwise, it
returns ERR.

ERRORS

None.
