Herror T_release_compute_device(const Htuple DeviceHandle)

void ReleaseComputeDevice(const HTuple& DeviceHandle)

void HComputeDevice::ReleaseComputeDevice() const

def release_compute_device(device_handle: HHandle) -> None

Description

release_compute_devicerelease_compute_deviceReleaseComputeDeviceReleaseComputeDevicerelease_compute_device closes a compute devices for the current HALCON thread and frees all resources associated to DeviceHandleDeviceHandleDeviceHandledeviceHandledevice_handle. release_compute_devicerelease_compute_deviceReleaseComputeDeviceReleaseComputeDevicerelease_compute_device 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_compute_devicerelease_compute_deviceReleaseComputeDeviceReleaseComputeDevicerelease_compute_device!

Execution Information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).
  • Multithreading scope: local (may only be called from the same thread in which the window, model, or tool instance was created).
  • Processed without parallelization.

Parameters

DeviceHandleDeviceHandleDeviceHandledeviceHandledevice_handle (input_control)  compute_device → HComputeDevice, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Compute device handle.

Result

release_compute_devicerelease_compute_deviceReleaseComputeDeviceReleaseComputeDevicerelease_compute_device returns the value 2 ( H_MSG_TRUE) if DeviceHandleDeviceHandleDeviceHandledeviceHandledevice_handle was closed successfully. Otherwise an exception will be raised.
