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.
