getrpcport - get RPC port number
int getrpcport(const char *host, unsigned long prognum,
unsigned long versnum, unsigned 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.
For an explanation of the terms used in this section, see attributes(7).
