39 Is a pointer to the window in which to set the timed blocking.
48 Is a Boolean expression.
57 Is the number of milliseconds to block or wait for input.
63 If \fIbool\fR is \fBTRUE\fR, the \fBnotimeout()\fR function disables a timer
64 used by \fBgetch\fR(3XCURSES) when handling multibyte function key sequences.
67 When \fIbool\fR is \fBFALSE\fR and keypad handling is enabled, a timer is set
68 by \fBgetch()\fR to handle bytes received that could be the beginning of a
69 function key (for example, ESC). If the remainder of the sequence is not
70 received before the time expires, the first byte is returned; otherwise, the
71 value of the function key is returned. Subsequent calls to the \fBgetch()\fR
72 function will return the other bytes received for the incomplete key sequence.
75 The \fBtimeout()\fR and \fBwtimeout()\fR functions set the length of time
76 \fBgetch()\fR waits for input for windows \fBstdscr\fR and \fIwin\fR,
77 respectively. These functions are similar to \fBnodelay\fR(3XCURSES) except
78 the time to block or wait for input can be specified.
81 A negative \fIdelay\fR causes the program to wait indefinitely for input; a
82 \fIdelay\fR of \fB0\fR returns \fBERR\fR if no input is ready; and a positive
83 \fIdelay\fR blocks until input arrives or the time specified expires, (in which
84 case, \fBERR\fR is returned).
88 On success, the \fBnotimeout()\fR function returns \fBOK\fR. Otherwise, it
92 The \fBtimeout()\fR and \fBwtimeout()\fR functions do not return a value.
