getrpcport - get RPC port number
#include <rpc/rpc.h>
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.
