//This service must be called in your module's Load(void) routine.
//descriptor.type can be a value other than the PROTOTYPE_ constants specified
//above to provide more precise positioning information for the contact
//protocol lists. It is strongly recommended that you give values relative to
//the constants, however, by adding or subtracting small integers ( <= 100).
//PROTOTYPE_PROTOCOL modules must not do this. The value must be exact.
//See MS_PROTO_ENUMPROTOCOLS for more notes.

Affect: Given a hContact, return the protocol that is registered for it, or NULL if no such protocol exists,
the returned string does not have to be freed and is valid even for multiple threads.
Note: Prior to 2004/09/28 this service WAS NOT THREAD SAFE and was slower
Note: Prior to 2004/09/28 this service would return NULL for a hContact if the protocol module
associated with the hContact was not currently loaded, no such check is performed now.
Version: 0.3.4 (2004/09/28)
