— Query settings of an I/O device instance.
Signature
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.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Parameters

(input_control) attribute.name(-array) →
HTupleMaybeSequence[str]HTupleHtuple (string) (string) (HString) (char*)
Parameter names.
Default:
'param_name'
"param_name"
"param_name"
"param_name"

Result
If the parameters are valid, the operator
get_io_device_paramget_io_device_paramGetIoDeviceParamGetIoDeviceParamGetIoDeviceParamget_io_device_param
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_infoGetExtendedErrorInfoGetExtendedErrorInfoGetExtendedErrorInfoget_extended_error_info
.
