getrpcport — get RPC port number
| int
            getrpcport( | char *host, | 
| int prognum, | |
| int versnum, | |
| int proto ); | 
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.
