getrpcport — get RPC port number
int
getrpcport( |
char * | host, |
| int | prognum, | |
| int | versnum, | |
| int | proto); |
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.
