Parameter and Runtime Settings Basic Functions

Function	Description
`DBR_SetModeArgument`	Set argument value for the specified mode parameter.
`DBR_GetModeArgument`	Get argument value for the specified mode parameter.
`DBR_GetRuntimeSettings`	Get current runtime settings.
`DBR_UpdateRuntimeSettings`	Modify and update the current runtime settings.
`DBR_ResetRuntimeSettings`	Reset runtime settings to default.

DBR_SetModeArgument

Set argument value for the specified mode parameter.

DBR_API int DBR_SetModeArgument (void* barcodeReader, const char* pModesName, const int index, const char* pArgumentName, const char* pArgumentValue, char errorMsgBuffer[], const int errorMsgBufferLen)

Parameters
[in] barcodeReader Handle of the barcode reader instance.
[in] pModesName The mode parameter name to set argument.
[in] index The array index of mode parameter to indicate a specific mode.
[in] pArgumentName The name of the argument to set.
[in] pArgumentValue The value of the argument to set.
[in,out] errorMsgBuffer The buffer is allocated by the caller and the recommended length is 256. The error message will be copied to the buffer.
[in] errorMsgBufferLen The length of the allocated buffer.

Return Value
Returns error code. Possible return(s): DBR_OK; DBRERR_SET_MODE_ARGUMENT_ERROR.
You can call DBR_GetErrorString to get detailed error message.

Code Snippet

char errorBuf[512];
DBR_InitLicense("YOUR-LICENSE-KEY", errorBuf, 512);
void* barcodeReader = DBR_CreateInstance();
PublicRuntimeSettings settings;
DBR_GetRuntimeSettings(barcodeReader, &settings);
settings.binarizationModes[0] = BM_LOCAL_BLOCK;
char errorMessage[256];
DBR_UpdateRuntimeSettings(barcodeReader, &settings, errorMessage, 256);
DBR_SetModeArgument(barcodeReader, "BinarizationModes", 0, "EnableFillBinaryVacancy", "1", errorMessage, 256);
DBR_DestroyInstance(barcodeReader);

DBR_GetModeArgument

Get argument value for the specified mode parameter.

DBR_API int DBR_GetModeArgument (void* barcodeReader, const char* pModesName, const int index, const char* pArgumentName, char valueBuffer[], const int valueBufferLen, char errorMsgBuffer[], const int errorMsgBufferLen)

Parameters
[in] barcodeReader Handle of the barcode reader instance.
[in] pModesName The mode parameter name to get argument.
[in] index The array index of mode parameter to indicate a specific mode.
[in] pArgumentName The name of the argument to get.
[in,out] valueBuffer The buffer is allocated by caller and the recommended length is 480. The argument value would be copied to the buffer.
[in] valueBufferLen The length of allocated buffer.
[in,out] errorMsgBuffer The buffer is allocated by the caller and the recommended length is 256. The error message will be copied to the buffer.
[in] errorMsgBufferLen The length of the allocated buffer.

Return Value
Returns error code. Possible return(s): DBR_OK; DBRERR_GET_MODE_ARGUMENT_ERROR.
You can call DBR_GetErrorString to get detailed error message.
