getrpcport - get RPC port number
int getrpcport(host, prognum, versnum, proto)
int prognum, versnum, 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.
To compile and link a program that calls this routine, follow the
procedures for section (3R) routines as described in intro (3).
