event_set - Prepare an event

SYNOPSIS

       bool event_set (resource  $event, mixed	$fd, int  $events, mixed  $callback, [mixed  $arg])

DESCRIPTION

	Prepares  the event to be used in event_add(3). The event is prepared to call the function specified by the $callback on the events speci-
       fied in parameter $events, which is a set of the following flags: EV_TIMEOUT, EV_SIGNAL, EV_READ, EV_WRITE and EV_PERSIST.

	If EV_SIGNAL bit is set in parameter $events, the $fd is interpreted as signal number.

	After initializing the event, use event_base_set(3) to associate the event with its event base.

	In case of matching event, these three arguments are passed to the $callback function:

	      o $fd
		- Signal number or resource indicating the stream.

	      o $events
		- A flag indicating the event. Consists of the following flags: EV_TIMEOUT, EV_SIGNAL, EV_READ, EV_WRITE and EV_PERSIST.

	      o $arg
		- Optional parameter, previously passed to event_set(3) as $arg.

PARAMETERS

	      o $event
		- Valid event resource.

	      o $fd
		- Valid PHP stream resource. The stream must be castable to file descriptor, so you most likely won't be able to use any  of  fil-
		tered streams.

	      o $events
		-  A  set of flags indicating the desired event, can be EV_READ and/or EV_WRITE. The additional flag EV_PERSIST makes the event to
		persist until event_del(3) is called, otherwise the callback is invoked only once.

	      o $callback
		- Callback function to be called when the matching event occurs.

	      o $arg
		- Optional callback parameter.

RETURN VALUES

       event_set(3) returns TRUE on success or FALSE on error.
