Name

get_io_device_paramT_get_io_device_paramGetIoDeviceParamGetIoDeviceParamget_io_device_param — Query settings of an I/O device instance.

Signature

get_io_device_param( : : IODeviceHandle, GenParamName : GenParamValue)

Description

get_io_device_paramget_io_device_paramGetIoDeviceParamGetIoDeviceParamGetIoDeviceParamget_io_device_param queries configuration settings of a specific device instance. The query parameters are passed in GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name, the corresponding configuration values are returned in GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value. IODeviceHandleIODeviceHandleIODeviceHandleIODeviceHandleIODeviceHandleiodevice_handle specifies the device returned 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.
