L_LTBAR_API L_INT L_BarCodeInit(nMajorType)
L_INT nMajorType; |
barcode major type |
Initializes the barcode engine and pre-loads the required DLL's for Barcode operations into memory.
| Parameter | Description | |
| nMajorType | Barcode major type. Values can be combined, when appropriate, by using a bitwise OR ( | ). Possible values are: | |
| Value | Meaning | |
| BARCODES_1D | [0x001] Initialize the linear barcode operations. | |
| BARCODES_PDF_READ | [0x008] Initialize the PDF barcode read operations. | |
| BARCODES_PDF_WRITE | [0x010] Initialize the PDF barcode write operations. | |
| BARCODES_DATAMATRIX_READ | [0x020] Initialize the Data Matrix barcode read operations. | |
| BARCODES_DATAMATRIX_WRITE | [0x040] Initialize the Data Matrix barcode write operations. | |
| BARCODES_QR_READ | [0x080] Initialize the QR barcode read operations. | |
| BARCODES_QR_WRITE | [0x100] Initialize the QR barcode write operations. | |
| BARCODES_MICRO_PDF_READ | [0x1000] Initialize the MicroPDF barcode read operations. | |
| BARCODES_MICRO_PDF_WRITE | [0x2000] Initialize the MicroPDF barcode write operations. | |
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
This function pre-loads the DLLs necessary for the specified barcode operations which can improve performance if you know what barcode types you plan on using. If a barcode major type is not initialized with this function you may still use it and the necessary DLLs will be loaded when L_BarCodeRead or L_BarCodeWrite is executed. This function must be called before calling any other Barcode functions. If L_BarCodeInit is called in an application, L_BarCodeExit must be called before terminating the application.
