+    that is being managed by an EFI Driver.

+

+  Arguments:

+    This             - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.

+    ControllerHandle - The handle of a controller that the driver specified by 

+                       This is managing.  This handle specifies the controller 

+                       whose name is to be returned.

+    ChildHandle      - The handle of the child controller to retrieve the name 

+                       of.  This is an optional parameter that may be NULL.  It 

+                       will be NULL for device drivers.  It will also be NULL 

+                       for a bus drivers that wish to retrieve the name of the 

+                       bus controller.  It will not be NULL for a bus driver 

+                       that wishes to retrieve the name of a child controller.

+    Language         - A pointer to a three character ISO 639-2 language

+                       driver writer.

+    ControllerName   - A pointer to the Unicode string to return.  This Unicode

+                       string is the name of the controller specified by 

+                       ControllerHandle and ChildHandle in the language specified

+                       by Language from the point of view of the driver specified
