74   Retrieves a Unicode string that is the user readable name of the controller
75   that is being managed by a driver.

77   This function retrieves the user readable name of the controller specified by
78   ControllerHandle and ChildHandle in the form of a Unicode string. If the
79   driver specified by This has a user readable name in the language specified by
80   Language, then a pointer to the controller name is returned in ControllerName,

91                                 specified by This is managing.  This handle
92                                 specifies the controller whose name is to be

94 
95   @param[in]   ChildHandle      The handle of the child controller to retrieve
96                                 the name of.  This is an optional parameter that
