* Create a channel for performing I/O on the file
* descriptor @fd. The particular subclass of QIOChannel
* that is returned will depend on what underlying object
* the file descriptor is associated with. It may be either
* a QIOChannelSocket or a QIOChannelFile instance. Upon
* success, the returned QIOChannel instance will own

* closing it when no longer required. On failure, the
* caller is responsible for closing @fd.

* Returns: the channel object, or NULL on error
