Libevent Functions
PHP Manual

event_buffer_new

Create new buffered event

Description

resource event_buffer_new ( resource $stream , mixed $readcb , mixed $writecb , mixed $errorcb [, mixed $arg ] )

Libevent provides an abstraction layer on top of the regular event API. Using buffered event you don't need to deal with the I/O manually, instead it provides input and output buffers that get filled and drained automatically.

Parameters

stream

Valid PHP stream resource. Must be castable to file descriptor.

readcb

Callback to invoke where there is data to read, or NULL if no callback is desired.

writecb

Callback to invoke where the descriptor is ready for writing, or NULL if no callback is desired.

errorcb

Callback to invoke where there is an error on the descriptor, cannot be NULL.

arg

An argument that will be passed to each of the callbacks (optional).

Return Values

event_buffer_new returns new buffered event resource on success or FALSE on error.
