getrpcport(3) get RPC port number


Ft int Fn getrpcport char *host int prognum int versnum int proto


The Fn getrpcport function returns the port number for version Fa versnum of the RPC program Fa prognum running on Fa host and using protocol Fa proto . It returns 0 if it cannot contact the portmapper, or if Fa prognum is not registered. If Fa prognum is registered but not with version Fa 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.


The Fn getrpcport function is part of libtirpc.
