<H2>DESCRIPTION</H2>
<B>getrpcport</B>()
returns the port number for version
<I>versnum</I>
of the RPC program
<I>prognum</I>
running on
<I>host</I>
and using protocol
<I>proto</I>.
It returns 0 if it cannot contact the portmapper, or if
<I>prognum</I>
is not registered.
If
<I>prognum</I>
is registered but not with version
<I>versnum</I>,
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.
