nodelay(3XCURSES) X/Open Curses Library Functions nodelay(3XCURSES) NAME
nodelay - set blocking or non-blocking read SYNOPSIS
cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib -R /usr/xpg4/lib -lcurses [ library... ] c89 [ flag... ] file... -lcurses [ library... ] #include <curses.h> int nodelay(WINDOW *win, bool bf); PARAMETERS
win Is a pointer to the window in which to enable non-blocking. bf Is a Boolean expression. DESCRIPTION
If enabled, (bf is TRUE), the nodelay() function causes getch(3XCURSES) to return ERR if no input is ready. When disabled, getch() blocks until a key is pressed. RETURN VALUES
On success, the nodelay() function returns OK. Otherwise, it returns ERR. ERRORS
None. ATTRIBUTES

notimeout(3XCURSES) X/Open Curses Library Functions notimeout(3XCURSES) NAME
notimeout, timeout, wtimeout - set timed blocking or non-blocking read SYNOPSIS
cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib -R /usr/xpg4/lib -lcurses [ library... ] c89 [ flag... ] file... -lcurses [ library... ] #include <curses.h> int notimeout(WINDOW *win, bool bf); void timeout(int delay); void wtimeout(WINDOW win, int delay); PARAMETERS
win Is a pointer to the window in which to set the timed blocking. bf Is a Boolean expression. delay Is the number of milliseconds to block or wait for input. DESCRIPTION
If bool is TRUE, the notimeout() function disables a timer used by getch(3XCURSES) when handling multibyte function key sequences. When bool is FALSE and keypad handling is enabled, a timer is set by getch() to handle bytes received that could be the beginning of a function key (for example, ESC). If the remainder of the sequence is not received before the time expires, the first byte is returned; otherwise, the value of the function key is returned. Subsequent calls to the getch() function will return the other bytes received for the incomplete key sequence. The timeout() and wtimeout() functions set the length of time getch() waits for input for windows stdscr and win, respectively. These functions are similar to nodelay(3XCURSES) except the time to block or wait for input can be specified. A negative delay causes the program to wait indefinitely for input; a delay of 0 returns ERR if no input is ready; and a positive delay blocks until input arrives or the time specified expires, (in which case, ERR is returned). RETURN VALUES
On success, the notimeout() function returns OK. Otherwise, it returns ERR. The timeout() and wtimeout() functions do not return a value. ERRORS
None. ATTRIBUTES
