+\r
+ Arguments:\r
+ This - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.\r
+ ControllerHandle - The handle of a controller that the driver specified by \r
+ This is managing. This handle specifies the controller \r
+ whose name is to be returned.\r
+ ChildHandle - The handle of the child controller to retrieve the name \r
+ of. This is an optional parameter that may be NULL. It \r
+ will be NULL for device drivers. It will also be NULL \r
+ for a bus drivers that wish to retrieve the name of the \r
+ bus controller. It will not be NULL for a bus driver \r
+ that wishes to retrieve the name of a child controller.\r
+ Language - A pointer to RFC3066 language identifier. \r
+ This is the language of the controller name \r
+ that that the caller is requesting, and it must match one\r
+ of the languages specified in SupportedLanguages. The \r
+ number of languages supported by a driver is up to the \r
+ driver writer.\r
+ ControllerName - A pointer to the Unicode string to return. This Unicode\r
+ string is the name of the controller specified by \r
+ ControllerHandle and ChildHandle in the language \r
+ specified by Language from the point of view of the \r
+ driver specified by This. \r
+\r
+ Returns:\r
+ EFI_SUCCESS - The Unicode string for the user readable name in the\r
+ language specified by Language for the driver \r
+ specified by This was returned in DriverName.\r
+ EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.\r
+ EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid \r
+ EFI_HANDLE.\r
+ EFI_INVALID_PARAMETER - Language is NULL.\r
+ EFI_INVALID_PARAMETER - ControllerName is NULL.\r
+ EFI_UNSUPPORTED - The driver specified by This is not currently \r
+ managing the controller specified by \r
+ ControllerHandle and ChildHandle.\r
+ EFI_UNSUPPORTED - The driver specified by This does not support the \r
+ language specified by Language.\r
