91 This function retrieves the user readable name of the controller specified by\r
92 ControllerHandle and ChildHandle in the form of a Unicode string. If the\r
93 driver specified by This has a user readable name in the language specified by\r
94 Language, then a pointer to the controller name is returned in ControllerName,\r

105 returned.\r
b4e73a63 106 @param ChildHandle The handle of the child controller to retrieve\r
62b9bb55 107 the name of. This is an optional parameter that\r
108 may be NULL. It will be NULL for device\r
109 drivers. It will also be NULL for a bus drivers\r
