描述
set_io_device_paramset_io_device_paramSetIoDeviceParamSetIoDeviceParamSetIoDeviceParamset_io_device_param (re)configures a specific device
instance. The configuration parameters are passed in
GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name, the corresponding values are passed in
GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value. IODeviceHandleIODeviceHandleIODeviceHandleIODeviceHandleIODeviceHandleiodevice_handle specifies the device
specified in open_io_deviceopen_io_deviceOpenIoDeviceOpenIoDeviceOpenIoDeviceopen_io_device。
Please check the directory doc/html/reference/io for
documentation about your specific I/O device interface, where all
supported device specific parameters are listed.
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。
参数
IODeviceHandleIODeviceHandleIODeviceHandleIODeviceHandleIODeviceHandleiodevice_handle (输入控制) io_device → HIODevice, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Handle of the opened I/O device.
