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


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

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.
