release_compute_deviceT_release_compute_deviceReleaseComputeDeviceReleaseComputeDevice (Operator)
Name
release_compute_deviceT_release_compute_deviceReleaseComputeDeviceReleaseComputeDevice — Close a compute_device.
Warning
release_compute_devicerelease_compute_deviceReleaseComputeDeviceReleaseComputeDeviceReleaseComputeDevice must not be used in HDevelop!
Signature
Description
release_compute_devicerelease_compute_deviceReleaseComputeDeviceReleaseComputeDeviceReleaseComputeDevice closes a compute devices for the current
HALCON thread and frees all resources associated to DeviceHandleDeviceHandleDeviceHandleDeviceHandledeviceHandle.
release_compute_devicerelease_compute_deviceReleaseComputeDeviceReleaseComputeDeviceReleaseComputeDevice 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_deviceReleaseComputeDeviceReleaseComputeDeviceReleaseComputeDevice!
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
DeviceHandleDeviceHandleDeviceHandleDeviceHandledeviceHandle (input_control) compute_device → HComputeDevice, HTupleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Compute device handle.
Result
release_compute_devicerelease_compute_deviceReleaseComputeDeviceReleaseComputeDeviceReleaseComputeDevice returns the value 2 (H_MSG_TRUE)
if DeviceHandleDeviceHandleDeviceHandleDeviceHandledeviceHandle was closed successfully. Otherwise
an exception will be raised.
