  • 發行項

發生錯誤時，就會發生此事件，例如掃描錯誤。 此事件的資料緩衝區如下所示。

Syntax

// Error occurred data should fill the ReadFile buffer in this order:
//    PosBarcodeScannerErrorOccurredEventData structure (length = sizeof(PosBarcodeScannerErrorOccurredEventData))
//    Error Message (length = MessageLength)
//    Scan Data (length = ScanDataLength)
//    Scan Data Label (length = ScanDataLabelLength)

typedef struct _PosBarcodeScannerErrorOccurredEventData
{
    PosEventDataHeader Header;
    LONG IsRetriable;
    UnifiedPosErrorSeverity Severity;
    UINT32 VendorErrorCode;
    UnifiedPosErrorReason Reason;
    UINT32 ExtendedReason;
    UINT32 MessageLength;
    PosBarcodeScannerDataReceivedEventData PartialData;
} PosBarcodeScannerErrorOccurredEventData;
