Name

clear_data_code_2d_modelT_clear_data_code_2d_modelClearDataCode2dModelClearDataCode2dModel — Delete a 2D data code model and free the allocated memory.

Signature

clear_data_code_2d_model( : : DataCodeHandle : )

Description

The operator clear_data_code_2d_modelclear_data_code_2d_modelClearDataCode2dModelClearDataCode2dModelClearDataCode2dModel deletes a 2D data code model that was created by create_data_code_2d_modelcreate_data_code_2d_modelCreateDataCode2dModelCreateDataCode2dModelCreateDataCode2dModel or read_data_code_2d_modelread_data_code_2d_modelReadDataCode2dModelReadDataCode2dModelReadDataCode2dModel. All memory used by the model is freed. The handle of the model is passed in DataCodeHandleDataCodeHandleDataCodeHandleDataCodeHandledataCodeHandle. After the operator call it is invalid.

For an explanation of the concept of the 2D data code reader see the introduction of chapter Identification / Data Code.

The value of this parameter may not be shared across multiple threads without external synchronization.

Parameters

DataCodeHandleDataCodeHandleDataCodeHandleDataCodeHandledataCodeHandle (input_control, state is modified) datacode_2d → (handle)

Handle of the 2D data code model.

Result

The operator clear_data_code_2d_modelclear_data_code_2d_modelClearDataCode2dModelClearDataCode2dModelClearDataCode2dModel returns the value 2 (H_MSG_TRUE) if a valid handle was passed and the referred 2D data code model can be freed correctly. Otherwise, an exception is raised.
