Опис

stream_set_blocking(resource $stream, bool $enable): bool

Sets blocking or non-blocking mode on a stream.

This function works for any stream that supports non-blocking mode (currently, regular files and socket streams).

Параметри

stream

The stream.

enable

If enable is false, the given stream will be switched to non-blocking mode, and if true, 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.

Значення, що повертаються

Повертає true у разі успіху або false в разі помилки.

Примітки

Зауваження:

On Windows, this has no affect on local files. Non-blocking IO for local files is not supported on Windows.
