Create new buffered event - Справочник: PHP5.4

Описание

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.
