Hi, After doing a fork and executing a shell, we execute (third party) commands which are essentially non-interactive. But some of them ask for input, under some (unforeseeable) circumstances. When this happens we go on waiting for output. Their is timeout, of course, but we don't seem to know...

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.
