Description

set_io_device_paramset_io_device_paramSetIoDeviceParamSetIoDeviceParamSetIoDeviceParam (re)configures a specific device instance. The configuration parameters are passed in GenParamNameGenParamNameGenParamNameGenParamNamegenParamName, the corresponding values are passed in GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue. IODeviceHandleIODeviceHandleIODeviceHandleIODeviceHandleIODeviceHandle specifies the device specified in open_io_deviceopen_io_deviceOpenIoDeviceOpenIoDeviceOpenIoDevice.

Please check the directory 'doc/html/reference/io'"doc/html/reference/io""doc/html/reference/io""doc/html/reference/io""doc/html/reference/io" for documentation about your specific I/O device interface, where all supported device specific parameters are listed.

Execution Information

Parameters

IODeviceHandleIODeviceHandleIODeviceHandleIODeviceHandleIODeviceHandle (input_control)  io_device → HIODevice, HTupleHTupleHtuple (integer) (IntPtr) (Hlong) (Hlong)

Handle of the opened I/O device.

GenParamNameGenParamNameGenParamNameGenParamNamegenParamName (input_control)  attribute.name(-array) → HTupleHTupleHtuple (string) (string) (HString) (char*)

Parameter names.

Default value: []

GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue (input_control)  attribute.value(-array) → HTupleHTupleHtuple (string / integer / real) (string / int / long / double) (HString / Hlong / double) (char* / Hlong / double)

Parameter values to set.

Default value: []

Result

If the parameters are valid, the operator set_io_device_paramset_io_device_paramSetIoDeviceParamSetIoDeviceParamSetIoDeviceParam returns the value 2 (H_MSG_TRUE). If necessary an exception is raised. In this case, an extended error information may be set and can be queried with the operator get_extended_error_infoget_extended_error_infoGetExtendedErrorInfoGetExtendedErrorInfoGetExtendedErrorInfo.
