Write a byte to the control socket of the controllable set.
This function is mostly useful for timer gstreamer.Poll objects created with
Poll.newTimer.
It will make any current and future Poll.wait function return with
1, meaning the control socket is set. After an equal amount of calls to
Poll.readControl have been performed, calls to Poll.wait will
block again until their timeout expired.
TRUE on success. FALSE when when the byte could not be written.
errno contains the detailed error code but will never be EAGAIN, EINTR or
EWOULDBLOCK. FALSE always signals a critical error.
