Routine Description:

    Determines what kind of transport on the current thread

Arguments:

    Type - Points to the type of binding if the functions succeeds.
           One of:
           TRANSPORT_TYPE_CN
           TRANSPORT_TYPE_DG
           TRANSPORT_TYPE_LPC
           TRANSPORT_TYPE_WMSG

Return Value:

    RPC_S_OK - The operation completed successfully.

    RPC_S_INVALID_BINDING - When the argument is not a binding handle.
