# socket_set_block

(PHP 4 >= 4.2.0, PHP 5)

socket_set_block — Sets blocking mode on a socket resource

### Descripción

bool socket_set_block ( resource `$socket` )

The socket_set_block() function removes 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 blocking socket, the script will pause its execution until it receives a signal or it can perform the operation.

### Lista de parámetros

`socket`

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

### Valores retornados

Devuelve `TRUE` si todo se llevó a cabo correctamente, `FALSE` en caso de fallo.

### Ejemplos

Example #1 socket_set_block() example

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

This example creates a listening socket on all interfaces on port 1223 and sets the socket to `O_BLOCK` mode. socket_accept() will hang until there is a connection to accept.
