Description Frees all resources associated with the handle.
If the handle was invalid, the functions returns silently. Any outstanding synchronous or asynchronous operations are canceled so their callback functions will not be called any longer. Since the RFC 2614 API does not provide function calls to for library initialization, OpenSLP keeps track of the number of SLPHandles that are open. Several global library data structures are initialized when the first SLPHandle is opened and maintained until the last SLPHandle is closed. If you can help it, DO NOT make a habit of opening and closing SLPHandles frequently.
