EventBuffer::pullup — Linearizes data within buffer and returns it's contents as a string

Descripción

public EventBuffer::pullup( int $size ): string

"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.

Advertencia

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

Parámetros

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

Valores devueltos

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