EventBuffer::pullup
(PECL event >= 1.2.6-beta)
EventBuffer::pullup — Linearizes data within buffer and returns it's contents as a string
Description
$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.
Calling EventBuffer::pullup() with a large size can be quite slow, since it potentially needs to copy the entire buffer's contents.
Return Values
If
size
is greater than the number of bytes in the buffer, the function returns
NULL. Otherwise,
EventBuffer::pullup()
returns string.
