Typedef Documentation

typedef EFI_STATUS(EFIAPI * EFI_COMPONENT_NAME2_GET_CONTROLLER_NAME)(IN EFI_COMPONENT_NAME2_PROTOCOL *This, IN EFI_HANDLE ControllerHandle, IN EFI_HANDLE ChildHandle, IN CHAR8 *Language, OUT CHAR16 **ControllerName)

Retrieves a string that is the user readable name of the controller that is being managed by an EFI Driver.

Parameters

This	A pointer to the EFI_COMPONENT_NAME2_PROTOCOL instance.
ControllerHandle	The handle of a controller that the driver specified by This is managing. This handle specifies the controller whose name is to be returned.
ChildHandle	The handle of the child controller to retrieve the name of. This is an optional parameter that may be NULL. It will be NULL for device drivers. It will also be NULL for bus drivers that wish to retrieve the name of the bus controller. It will not be NULL for a bus driver that wishes to retrieve the name of a child controller.
Language	A pointer to a Null-terminated ASCII string array indicating the language. This is the language of the driver name that the caller is requesting, and it must match one of the languages specified in SupportedLanguages. The number of languages supported by a driver is up to the driver writer. Language is specified in RFC 4646 language code format.
ControllerName	A pointer to the string to return. This string is the name of the controller specified by ControllerHandle and ChildHandle in the language specified by Language from the point of view of the driver specified by This.

Return values

EFI_SUCCESS	The string for the user readable name in the language specified by Language for the driver specified by This was returned in DriverName.
EFI_INVALID_PARAMETER	ControllerHandle is NULL.
EFI_INVALID_PARAMETER	ChildHandle is not NULL and it is not a valid EFI_HANDLE.
EFI_INVALID_PARAMETER	Language is NULL.
EFI_INVALID_PARAMETER	ControllerName is NULL.
EFI_UNSUPPORTED	The driver specified by This is not currently managing the controller specified by ControllerHandle and ChildHandle.
EFI_UNSUPPORTED	The driver specified by This does not support the language specified by Language.

typedef EFI_STATUS(EFIAPI * EFI_COMPONENT_NAME2_GET_DRIVER_NAME)(IN EFI_COMPONENT_NAME2_PROTOCOL *This, IN CHAR8 *Language, OUT CHAR16 **DriverName)

Retrieves a string that is the user readable name of the EFI Driver.

Parameters

This	A pointer to the EFI_COMPONENT_NAME2_PROTOCOL instance.
Language	A pointer to a Null-terminated ASCII string array indicating the language. This is the language of the driver name that the caller is requesting, and it must match one of the languages specified in SupportedLanguages. The number of languages supported by a driver is up to the driver writer. Language is specified in RFC 4646 language code format.
DriverName	A pointer to the string to return. This string is the name of the driver specified by This in the language specified by Language.

Return values

EFI_SUCCESS	The string for the Driver specified by This and the language specified by Language was returned in DriverName.
EFI_INVALID_PARAMETER	Language is NULL.
EFI_INVALID_PARAMETER	DriverName is NULL.
EFI_UNSUPPORTED	The driver specified by This does not support the language specified by Language.
