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.
