OTPortRef OTGetProviderPortRef(ProviderRef ref);
C++ INTERFACE
OTPortRef TProvider::GetOTPortRef();
PARAMETERS

ref
The provider for which you wish to obtain the port.
function result

The OTGetProviderPortRef function returns the port reference for the provider identified by the ref parameter. If the function returns kOTInvalidPortRef, then either no port was associated with this provider or there were multiple associated ports and Open Transport did not know which to return.
