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. | ||
