110 Routine Description:\r
111 Retrieves a Unicode string that is the user readable name of the controller\r
112 that is being managed by an EFI Driver.\r
113\r
114 Arguments:\r
115 This - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.\r
116 ControllerHandle - The handle of a controller that the driver specified by \r
117 This is managing. This handle specifies the controller \r
118 whose name is to be returned.\r
119 ChildHandle - The handle of the child controller to retrieve the name \r
120 of. This is an optional parameter that may be NULL. It \r
121 will be NULL for device drivers. It will also be NULL \r
122 for a bus drivers that wish to retrieve the name of the \r
123 bus controller. It will not be NULL for a bus driver \r
124 that wishes to retrieve the name of a child controller.\r
125 Language - A pointer to a three character ISO 639-2 language \r
126 identifier. This is the language of the controller name \r
127 that that the caller is requesting, and it must match one\r
128 of the languages specified in SupportedLanguages. The \r
129 number of languages supported by a driver is up to the \r
130 driver writer.\r
131 ControllerName - A pointer to the Unicode string to return. This Unicode\r
132 string is the name of the controller specified by \r
133 ControllerHandle and ChildHandle in the language specified\r
134 by Language from the point of view of the driver specified\r
135 by This. \r
136\r
137 Returns:\r
138 EFI_SUCCESS - The Unicode string for the user readable name in the \r
139 language specified by Language for the driver \r
140 specified by This was returned in DriverName.\r
141 EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.\r
142 EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid EFI_HANDLE.\r
143 EFI_INVALID_PARAMETER - Language is NULL.\r
144 EFI_INVALID_PARAMETER - ControllerName is NULL.\r
145 EFI_UNSUPPORTED - The driver specified by This is not currently managing \r
146 the controller specified by ControllerHandle and \r
147 ChildHandle.\r
148 EFI_UNSUPPORTED - The driver specified by This does not support the \r
149 language specified by Language.\r
