2025-02-27

EventBuffer::copyout

(PECL event >= 1.2.6-beta)

EventBuffer::copyoutCopies out specified number of bytes from the front of the buffer

说明

public EventBuffer::copyout( string &$data , int $max_bytes ): int

Behaves just like EventBuffer::read() , but does not drain any data from the buffer. I.e. it copies the first max_bytes bytes from the front of the buffer into data . If there are fewer than max_bytes bytes available, the function copies all the bytes there are.

参数

data

Output string.

max_bytes

The number of bytes to copy.

返回值

Returns the number of bytes copied, or -1 on failure.
