描述

release_all_compute_devicesrelease_all_compute_devicesReleaseAllComputeDevicesReleaseAllComputeDevicesReleaseAllComputeDevicesrelease_all_compute_devices closes all compute devices for the current HALCON thread and frees all associated resources. release_all_compute_devicesrelease_all_compute_devicesReleaseAllComputeDevicesReleaseAllComputeDevicesReleaseAllComputeDevicesrelease_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_devicesrelease_all_compute_devicesReleaseAllComputeDevicesReleaseAllComputeDevicesReleaseAllComputeDevicesrelease_all_compute_devices.

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 未采用并行化处理。

结果

release_all_compute_devicesrelease_all_compute_devicesReleaseAllComputeDevicesReleaseAllComputeDevicesReleaseAllComputeDevicesrelease_all_compute_devices 返回值 2 ( H_MSG_TRUE) if all devices were closed successfully.否则将抛出异常。
