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.

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

|
|
@param 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 3066 or ISO 639-2 language code format.

specified by Language.

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

|
RFC 3066 or ISO 639-2 language code format.
|
|
|
|
@param 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.
|
|
|
|
@retval EFI_SUCCESS The Unicode string for the user readable name in
|
|
the language specified by Language for the

|
|
@retval EFI_INVALID_PARAMETER ControllerName is NULL.
