Description
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:
-
fd -
Signal number or resource indicating the stream.
-
events -
A flag indicating the event. Consists of the following flags:
EV_TIMEOUT,EV_SIGNAL,EV_READ,EV_WRITEandEV_PERSIST. -
arg -
Optional parameter, previously passed to event_set() as
arg.
Parameters
-
event -
Valid event resource.
-
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 filtered streams.
-
events -
A set of flags indicating the desired event, can be
EV_READand/orEV_WRITE. The additional flagEV_PERSISTmakes the event to persist until event_del() is called, otherwise the callback is invoked only once. -
callback -
Callback function to be called when the matching event occurs.
-
arg -
Optional callback parameter.
