clear_all_bar_code_models( : : : )
The operator clear_all_bar_code_models deletes all bar code models that were created by create_bar_code_model. All memory used by the models is freed. After the operator call, all bar code handles are invalid.
clear_all_bar_code_models exists solely for the purpose of implementing the “reset program” functionality in HDevelop. clear_all_bar_code_models must not be used in any application.
The operator clear_all_bar_code_models returns the value 2 (H_MSG_TRUE) if all bar code models were freed correctly. Otherwise, an exception will be raised.
