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.
|
|
|
|
|
|
|
|
|
|
@param[in] This A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
|
|
|
|
|
EFI_COMPONENT_NAME_PROTOCOL instance.
|
|
|
|
|
|
|
|
|
|
@param[in] 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.
|
|
|
|
|
|
|
|
|
|
@param[in] 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 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.
|
|
|
|
|
|
|
|
|
|
@param[in] 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 the
|
|
|

|
RFC 4646 or ISO 639-2 language code format.
|
|
|

|
|
|
|
|
controller specified by ControllerHandle and
|
|
|
|
|
ChildHandle in the language specified by
|
|
|
|

|
|
|
|
|
