EventBuffer::read — Read data from an evbuffer and drain the bytes read

説明

public EventBuffer::read( int $max_bytes ): string

Read the first max_bytes from the buffer and drain the bytes read. If more max_bytes are requested than are available in the buffer, it only extracts as many bytes as available.

パラメータ

max_bytes: Maxmimum number of bytes to read from the buffer.

戻り値

Returns string read, or false on failure.

バージョン	説明
PECL event 1.6.0	Renamed EventBuffer::read()(the old method name) to EventBuffer::read(). EventBuffer::read() now takes only `max_bytes` argument; returns string instead of integer.
