Subject: Implement #43269: Retrieve FD_SETSIZE within PHP
X-Git-Tag: php-7.1.0beta1~146
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=10e824808259dedf537ededabb9812dcae5785b5;p=php

Implement #43269: Retrieve FD_SETSIZE within PHP

To give userland developers who work with large numbers of file descriptors
the opportunity to avoid problems on systems which may not support that
many descriptors (e.g. when calling socket_select()), we make FD_SETSIZE
available in PHP as PHP_FD_SETSIZE.
