<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.
