getrpcport()  returns  the port number for version versnum of the RPC program prognum running on host and
       using protocol proto.  It returns 0 if it cannot contact the portmapper, or if prognum is not registered.
       If prognum is registered but not with version versnum, it will still  return  a  port  number  (for  some
       version  of  the program) indicating that the program is indeed registered.  The version mismatch will be
       detected upon the first call to the service.
