## DESCRIPTION

The `MrmFetchWidgetOverride` function
is the extended version of `MrmFetchWidget`. It is identical to `MrmFetchWidget`, except that it allows the caller to override the widget's name and any arguments that `MrmFetchWidget` would otherwise retrieve from the UID file or one of the defaulting mechanisms. That is, the override argument list is not limited to those arguments in the UID file.

The override arguments apply only to the widget fetched and returned by this function. Its children (subtree) do not receive any override parameters.

hierarchy_id

- Specifies the ID of the UID hierarchy that contains the interface definition. The value of hierarchy_id was returned in a previous call to `MrmOpenHierarchyPerDisplay`.

index

- Specifies the UIL name of the widget to fetch.

parent_widget

- Specifies the parent widget ID.

override_name

- Specifies the name to override the widget name. Use a NULL value if you do not want to override the widget name.

override_args

- Specifies the override argument list, exactly as given to `XtCreateWidget` (conversion complete and so forth). Use a NULL value if you do not want to override the argument list.

override_num_args

- Specifies the number of arguments in override_args.

widget

- Returns the widget ID of the created widget.

class

- Returns the class code identifying MRM's widget class. Literals identifying MRM widget class codes are defined in the include file `Mrm/MrmPublic.h`.

## RETURN VALUE

This function returns one of the following status return constants:

`MrmSUCCESS`

- The function executed successfully.

`MrmBAD_HIERARCHY`

- The hierarchy ID was invalid.

`MrmNOT_FOUND`

- The widget was not found in UID hierarchy.

`MrmFAILURE`

- The function failed.
