event_set — Prepare an event
Prepares the event to be used in event_add(). The event
is prepared to call the function specified by the callback
on the events specified 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() to associate the event with its event base.
In case of matching event, these three arguments are passed to the
callback function:
fdSignal number or resource indicating the stream.
events
A flag indicating the event. Consists of the following flags:
EV_TIMEOUT, EV_SIGNAL,
EV_READ, EV_WRITE
and EV_PERSIST.
arg
Optional parameter, previously passed to event_set()
as arg.
eventValid event resource.
fdValid PHP stream resource. The stream must be castable to file descriptor, so you most likely won't be able to use any of filtered streams.
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() is called, otherwise
the callback is invoked only once.
callbackCallback function to be called when the matching event occurs.
argOptional callback parameter.
event_set() returns TRUE on success or FALSE on error.
