stream_set_blocking — Set blocking/non-blocking mode on a stream
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).
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.
Hinweis:
On Windows, this has no affect on local files. Non-blocking IO for local files is not supported on Windows.
