    //  - VmbErrorSuccess:       If no error
    //  - VmbErrorApiNotStarted: VmbStartup() was not called before the current command
    //
    // Details:     This function can only succeed if the given frame has been filled by the API.

    // Details:     After reading the ancillary data and before re-queuing the frame, ancillary data
    //              must be closed.
