/**
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.
@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
RFC 4646 or ISO 639-2 language code format.
@param[out] ControllerName 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.
@retval 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.
@retval EFI_INVALID_PARAMETER ControllerHandle is NULL.
@retval EFI_INVALID_PARAMETER ChildHandle is not NULL and it is not a valid
EFI_HANDLE.
@retval EFI_INVALID_PARAMETER Language is NULL.
@retval EFI_INVALID_PARAMETER ControllerName is NULL.
@retval EFI_UNSUPPORTED The driver specified by This is not currently
managing the controller specified by
ControllerHandle and ChildHandle.
@retval EFI_UNSUPPORTED The driver specified by This does not support
the language specified by Language.
