+.SH DESCRIPTION
+.BR getrpcport ()
+returns the port number for version
+.I versnum
+of the RPC program
+.I prognum
+running on
+.I host
+and using protocol
+.IR proto .
+It returns 0 if it cannot contact the portmapper, or if
+.I prognum
+is not registered.
+If
+.I prognum
+is registered but not with version
+.IR 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.
