GETRPCPORT(3) BSD Programmer's Manual GETRPCPORT(3)
getrpcport - get RPC port number
#include <rpc/rpc.h> int getrpcport(char *host, int prognum, int versnum, int proto);
getrpcport() returns the port number for version versnum of the RPC pro- gram 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 pro- gram is indeed registered. The version mismatch will be detected upon the first call to the service. MirOS BSD #10-current October 6, 1987 1
