release_compute_deviceT_release_compute_deviceReleaseComputeDeviceReleaseComputeDevicerelease_compute_device (Operator)

Name

release_compute_deviceT_release_compute_deviceReleaseComputeDeviceReleaseComputeDevicerelease_compute_device — Close a compute_device.

Warning

release_compute_devicerelease_compute_deviceReleaseComputeDeviceReleaseComputeDevicerelease_compute_device must not be used in HDevelop!

Signature

release_compute_device( : : DeviceHandle : )

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 → (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.
