getrpcport(3) -- Linux man page
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.
