签名
def control_io_device(iodevice_handle: HHandle, action: str, argument: MaybeSequence[Union[int, float, str]]) -> Sequence[Union[int, float, str]]
描述
control_io_devicecontrol_io_deviceControlIoDeviceControlIoDeviceControlIoDevicecontrol_io_device performs an action on the I/O device. The
supported parameters are interface-specific and listed in the
corresponding documentation of the used I/O interface that can be
found in the directory doc/html/reference/io.
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.

结果
如果参数有效，算子 control_io_devicecontrol_io_deviceControlIoDeviceControlIoDeviceControlIoDevicecontrol_io_device 返回值 2 ( H_MSG_TRUE )。如有必要，则抛出异常。 In this
case an extended error information may be set and can be queried with
the operator get_extended_error_infoget_extended_error_infoGetExtendedErrorInfoGetExtendedErrorInfoGetExtendedErrorInfoget_extended_error_info。
