# socket_set_blocking

(PHP 4 >= 4.0.0)

socket_set_blocking -- Set blocking/non-blocking mode on a socket

## Description

``int socket_set_blocking` (int socket descriptor, int mode)`

If `mode` is `FALSE`, the given socket descriptor will be switched to non-blocking mode, and if `TRUE`, it will be switched to blocking mode. This affects calls like fgets() that read from the socket. In non-blocking mode an fgets() call will always return right away while in blocking mode it will wait for data to become available on the socket.

This function was previously called as set_socket_blocking() but this usage is deprecated.
