pcntl_sigtimedwait - Waits for signals, with a timeout

SYNOPSIS

       int pcntl_sigtimedwait (array  $set, [array  &$siginfo], [int  $seconds], [int  $nanoseconds])

DESCRIPTION

	The  pcntl_sigtimedwait(3)  function  operates in exactly the same way as pcntl_sigwaitinfo(3) except that it takes two additional parame-
       ters, $seconds and $nanoseconds, which enable an upper bound to be placed on the time for which the script is suspended.

PARAMETERS

	      o $set
		- Array of signals to wait for.

	      o $siginfo
		- The $siginfo is set to an array containing informations about the signal. See pcntl_sigwaitinfo(3).

	      o $seconds
		- Timeout in seconds.

	      o $nanoseconds
		- Timeout in nanoseconds.

RETURN VALUES

	On success, pcntl_sigtimedwait(3) returns a signal number.

pcntl_signal_dispatch - Calls signal handlers for pending signals

SYNOPSIS

       bool pcntl_signal_dispatch (void  )

	The pcntl_signal_dispatch(3) function calls the signal handlers installed by pcntl_signal(3) for each pending signal.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      pcntl_signal_dispatch(3) example

	      <?php
	      echo "Installing signal handler...
";
	      pcntl_signal(SIGHUP,  function($signo) {
		   echo "signal handler called
";
	      });

	      echo "Generating signal SIGHUP to self...
";
	      posix_kill(posix_getpid(), SIGHUP);

	      echo "Dispatching...
";
	      pcntl_signal_dispatch();

	      echo "Done
";

	      ?>

	      The above example will output something similar to:

	      Installing signal handler...
	      Generating signal SIGHUP to self...
	      Dispatching...
	      signal handler called
	      Done
