NAME
       getrpcport - get RPC port number

SYNOPSIS
       int getrpcport(host, prognum, versnum, proto)
	    char *host;
	    int prognum, versnum, proto;

DESCRIPTION
       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.
