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 pro‐
gram. 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.
