# socket_set_nonblock

(PHP 4 >= 4.0.7, PHP 5)

socket_set_nonblock — Sets nonblocking mode for file descriptor fd

### Описание

bool socket_set_nonblock ( resource `$socket` )

The socket_set_nonblock() function sets the `O_NONBLOCK` flag on the socket specified by the `socket` parameter.

When an operation (e.g. receive, send, connect, accept, ...) is performed on a non-blocking socket, the script not pause its execution until it receives a signal or it can perform the operation. Rather, if the operation would result in a block, the called function will fail.

### Список параметров

`socket`

  A valid socket resource created with socket_create() or socket_accept().

### Возвращаемые значения

Возвращает `TRUE` в случае успешного завершения или `FALSE` в случае возникновения ошибки.

### Примеры

Пример #1 socket_set_nonblock() example

`<?php
$socket = socket_create_listen(1223);
socket_set_nonblock($socket);
socket_accept($socket);
?>`

This example creates a listening socket on all interfaces on port 1223 and sets the socket to `O_NONBLOCK` mode. socket_accept() will immediately fail unless there is a pending connection exactly at this moment.
