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.
运行信息
