stream_set_blocking

(PHP 4 >= 4.3.0, PHP 5)

stream_set_blocking — Set blocking/non-blocking mode on a stream

Description

bool stream_set_blocking ( resource $stream , int $mode )

If mode is 0, the given stream will be switched to non-blocking mode, and if 1, it will be switched to blocking mode. This affects calls like fgets() and fread() that read from the stream. 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 stream.

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

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

Замечание: Prior to PHP 4.3, this function only worked on socket based streams. Since PHP 4.3, this function works for any stream that supports non-blocking mode (currently, regular files and socket streams).
