- Routine Description:\r
- Retrieves a Unicode string that is the user readable name of the controller\r
- that is being managed by an EFI Driver.\r
-\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 a three character ISO 639-2 language \r
- identifier. 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 specified\r
- by Language from the point of view of the driver specified\r
- 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 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 managing \r
- the controller specified by ControllerHandle and \r
- ChildHandle.\r
- EFI_UNSUPPORTED - The driver specified by This does not support the \r
- language specified by Language.\r
