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

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

Parameters

stream

The stream.

mode

If mode 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.

Notes

Note:

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

Note:

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