Routine Description:

|

Retrieves a Unicode string that is the user readable name of the controller

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

string is the name of the controller specified by

|

specified by Language from the point of view of the

driver specified by This.

EFI_INVALID_PARAMETER - ControllerName is NULL.
