(PECL libevent >= 0.0.1)

event_buffer_new — Create new buffered event

说明

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

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.

参数

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).

返回值

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