Routine Description:

    This routine is called when a transaction SMB is completed.

Arguments:

    IN PVOID OutSetup - Response setup words
    IN CLONG OutSetupCount - Length of response setup in bytes

    IN PVOID OutParam - Response parameters
    IN CLONG OutParameterCount - Size of response parameters in bytes

    IN PVOID OutData - Response data
    IN CLONG OutDataCount - Size of response data in bytes.

Return Value:

    NTSTATUS - Status of request
