◆ QemuVideoComponentNameGetControllerName()

EFI_STATUS EFIAPI QemuVideoComponentNameGetControllerName	(	IN EFI_COMPONENT_NAME_PROTOCOL *	This,
		IN EFI_HANDLE	ControllerHandle,
		IN EFI_HANDLE ChildHandle	OPTIONAL,
		IN CHAR8 *	Language,
		OUT CHAR16 **	ControllerName
	)

Retrieves a Unicode string that is the user readable name of the controller that is being managed by a driver.

This function retrieves the user readable name of the controller specified by ControllerHandle and ChildHandle in the form of a Unicode string. If the driver specified by This has a user readable name in the language specified by Language, then a pointer to the controller name is returned in ControllerName, and EFI_SUCCESS is returned. If the driver specified by This is not currently managing the controller specified by ControllerHandle and ChildHandle, then EFI_UNSUPPORTED is returned. If the driver specified by This does not support the language specified by Language, then EFI_UNSUPPORTED is returned.

Parameters

This[in]	A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or EFI_COMPONENT_NAME_PROTOCOL instance.
ControllerHandle[in]	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[in]	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 a 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[in]	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 or ISO 639-2 language code format.
ControllerName[out]	A pointer to the Unicode string to return. This Unicode 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 Unicode 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 not a valid EFI_HANDLE.
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.

	)

Retrieves a Unicode string that is the user readable name of the driver.

This function retrieves the user readable name of a driver in the form of a Unicode string. If the driver specified by This has a user readable name in the language specified by Language, then a pointer to the driver name is returned in DriverName, and EFI_SUCCESS is returned. If the driver specified by This does not support the language specified by Language, then EFI_UNSUPPORTED is returned.

Parameters

This[in]	A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or EFI_COMPONENT_NAME_PROTOCOL instance.
Language[in]	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 or ISO 639-2 language code format.
DriverName[out]	A pointer to the Unicode string to return. This Unicode string is the name of the driver specified by This in the language specified by Language.

Return values

EFI_SUCCESS	The Unicode 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.
