26 win Is a pointer to the window in which to set the timed blocking.
27
28
29 bf Is a Boolean expression.
30
31
32 delay Is the number of milliseconds to block or wait for input.

34
36 If bool is TRUE, the notimeout() function disables a timer used by
37 getch(3XCURSES) when handling multibyte function key sequences.
38
39
40 When bool is FALSE and keypad handling is enabled, a timer is set by
41 getch() to handle bytes received that could be the beginning of a func‐
42 tion key (for example, ESC). If the remainder of the sequence is not
43 received before the time expires, the first byte is returned; other‐
44 wise, the value of the function key is returned. Subsequent calls to
45 the getch() function will return the other bytes received for the
46 incomplete key sequence.
47
48
49 The timeout() and wtimeout() functions set the length of time getch()
50 waits for input for windows stdscr and win, respectively. These func‐
51 tions are similar to nodelay(3XCURSES) except the time to block or
52 wait for input can be specified.
53
54
55 A negative delay causes the program to wait indefinitely for input; a
56 delay of 0 returns ERR if no input is ready; and a positive delay
57 blocks until input arrives or the time specified expires, (in which
58 case, ERR is returned).
59
61 On success, the notimeout() function returns OK. Otherwise, it returns
62 ERR.
63
64
65 The timeout() and wtimeout() functions do not return a value.
66
68 None.
