+ Retrieves a Unicode string that is the user readable name of the controller\r
+ that is being managed by a driver.\r
+\r
+ This function retrieves the user readable name of the controller specified by\r
+ ControllerHandle and ChildHandle in the form of a Unicode string. If the\r
+ driver specified by This has a user readable name in the language specified by\r
+ Language, then a pointer to the controller name is returned in ControllerName,\r
+ and EFI_SUCCESS is returned. If the driver specified by This is not currently\r
+ managing the controller specified by ControllerHandle and ChildHandle,\r
+ then EFI_UNSUPPORTED is returned. If the driver specified by This does not\r
+ support the language specified by Language, then EFI_UNSUPPORTED is returned.\r
+\r
+ @param[in] This A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or\r
+ EFI_COMPONENT_NAME_PROTOCOL instance.\r
+\r
+ @param[in] ControllerHandle The handle of a controller that the driver\r
+ specified by This is managing. This handle\r
+ specifies the controller whose name is to be\r
+ returned.\r
+\r
+ @param[in] ChildHandle The handle of the child controller to retrieve\r
+ the name of. This is an optional parameter that\r
+ may be NULL. It will be NULL for device\r
+ drivers. It will also be NULL for a bus drivers\r
+ that wish to retrieve the name of the bus\r
+ controller. It will not be NULL for a bus\r
+ driver that wishes to retrieve the name of a\r
+ child controller.\r
+\r
+ @param[in] Language A pointer to a Null-terminated ASCII string\r
+ array indicating the language. This is the\r
+ language of the driver name that the caller is\r
+ requesting, and it must match one of the\r
+ languages specified in SupportedLanguages. The\r
+ number of languages supported by a driver is up\r
+ to the driver writer. Language is specified in\r
+ RFC 4646 or ISO 639-2 language code format.\r
+\r
+ @param[out] ControllerName A pointer to the Unicode string to return.\r
+ This Unicode string is the name of the\r
+ controller specified by ControllerHandle and\r
+ ChildHandle in the language specified by\r
+ Language from the point of view of the driver\r
+ specified by This.\r
+\r
+ @retval EFI_SUCCESS The Unicode string for the user readable name in\r
+ the language specified by Language for the\r
+ driver specified by This was returned in\r
+ DriverName.\r
+\r
+ @retval EFI_INVALID_PARAMETER ControllerHandle is NULL.\r
+\r
+ @retval EFI_INVALID_PARAMETER ChildHandle is not NULL and it is not a valid\r
+ EFI_HANDLE.\r
+\r
+ @retval EFI_INVALID_PARAMETER Language is NULL.\r
+\r
+ @retval EFI_INVALID_PARAMETER ControllerName is NULL.\r
+\r
+ @retval EFI_UNSUPPORTED The driver specified by This is not currently\r
+ managing the controller specified by\r
+ ControllerHandle and ChildHandle.\r
+\r
+ @retval EFI_UNSUPPORTED The driver specified by This does not support\r
+ the language specified by Language.\r
