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

Beschreibung

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).

Parameter-Liste

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.

Rückgabewerte

Gibt bei Erfolg true zurück. Bei einem Fehler wird false zurückgegeben.

Anmerkungen

Hinweis:

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