getrpcport(3) Library Functions Manual getrpcport(3) NAME getrpcport - get RPC port number LIBRARY Standard C library (libc, -lc) SYNOPSIS #include <rpc/rpc.h> int getrpcport(const char *host, unsigned long prognum, unsigned long versnum, unsigned int 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 de- tected upon the first call to the service.
