Sets blocking or non-blocking mode on a <parameter>stream</parameter>.

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

If <parameter>mode</parameter> 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
<function>fgets</function> and <function>fread</function>
that read from the stream. In non-blocking mode an
<function>fgets</function> call will always return right away
while in blocking mode it will wait for data to become available
on the stream.
