inotify_queue_len - Return a number upper than zero if there are pending events

SYNOPSIS

       int inotify_queue_len (resource	$inotify_instance)

DESCRIPTION

	This  function	allows to know if inotify_read(3) will block or not. If a number upper than zero is returned, there are pending events and
       inotify_read(3) will not block.

PARAMETERS

	      o $inotify_instance
		- Resource returned by inotify_init(3)

RETURN VALUES

	Returns a number upper than zero if there are pending events.

SEE ALSO

       inotify_init(3), stream_select(3), stream_set_blocking(3).

SOCKET_SET_NONBLOCK(3)							 1						    SOCKET_SET_NONBLOCK(3)

socket_set_nonblock - Sets nonblocking mode for file descriptor fd

SYNOPSIS

       bool socket_set_nonblock (resource  $socket)

DESCRIPTION

	The socket_set_nonblock(3) function sets the O_NONBLOCK flag on the socket specified by the $socket parameter.

	When  an  operation (e.g. receive, send, connect, accept, ...) is performed on a non-blocking socket, the script will not pause its execu-
       tion until it receives a signal or it can perform the operation. Rather, if the operation would result in a block, the called function will
       fail.

PARAMETERS

	      o $socket
		- A valid socket resource created with socket_create(3) or socket_accept(3).

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      socket_set_nonblock(3) example

	      <?php
	      $socket = socket_create_listen(1223);
	      socket_set_nonblock($socket);

	      socket_accept($socket);
	      ?>

	       This  example  creates  a  listening socket on all interfaces on port 1223 and sets the socket to O_NONBLOCK mode. socket_accept(3)
	      will immediately fail unless there is a pending connection exactly at this moment.
