.Ft int

|
.Sh DESCRIPTION
|
|
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.
