#include "ltbar.h"

L_INT EXT_FUNCTION L_BarCodeInit(nMajorType)

L_INT nMajorType;

/* Barcode major type */

Initializes the barcode engine and 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

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

This function initializes the LEADTOOLS Barcode DLL's. Also, this function will load the required DLLs for Barcode operations into memory. 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.
