release_all_compute_devices — Close all compute devices.
release_all_compute_devices must not be used in HDevelop!
release_all_compute_devices( : : : )
release_all_compute_devices closes all compute devices for the current HALCON thread and frees all associated resources. release_all_compute_devices is solely for the purpose of freeing all device related resources before unloading the HALCON library, if the library was loaded using a mechanism like LoadLibrary or dlopen. In all other cases you must not use release_all_compute_devices.
release_all_compute_devices returns the value 2 (H_MSG_TRUE) if all devices were closed successfully. Otherwise an exception will be raised.
