Routine Description:
|
|
|
|
Retrieves a Unicode string that is the user readable name of the EFI Driver.
|
|
|
|
Arguments:
|
|
|
|
This - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.
|
|
Language - A pointer to a three character ISO 639-2 language identifier.
|
|
This is the language of the driver name that 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.
|
|
DriverName - 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.
|
|
|
|
Returns:
|
|
|
|
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.
|
|
EFI_UNSUPPORTED - The driver specified by This does not support the
|
|
language specified by Language.

Routine Description:
|
|
|
|
Retrieves a Unicode string that is the user readable name of the controller
|
|
that is being managed by an EFI Driver.
|
|
|
|
Arguments:
|
|
|
|
This - A pointer to the EFI_COMPONENT_NAME_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 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 - A pointer to a three character ISO 639-2 language
|
|
identifier. This is the language of the controller name
|
|
that 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.
|
|
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.
|
|
|
|
Returns:
|
|
|
|
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.
