DESCRIPTION

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

25
26       The nocbreak(3XCURSES) function should  be  used  to  leave  half-delay
27       mode.
