EventBuffer::pullup

Linearizes data within buffer and returns it's contents as a string

説明

public string EventBuffer::pullup( int $size )

"Linearizes" the first size bytes of the buffer, copying or moving them as needed to ensure that they are all contiguous and occupying the same chunk of memory. If size is negative, the function linearizes the entire buffer.

警告

Calling EventBuffer::pullup with a large size can be quite slow, since it potentially needs to copy the entire buffer's contents.

パラメータ

size

The number of bytes required to be contiguous within the buffer.

戻り値

If size is greater than the number of bytes in the buffer, the function returns null. Otherwise, EventBuffer::pullup returns string.
