|
|
in SupportedLanguages. The number of languages supported by a

EFI_SUCCESS - The Unicode string for the Driver specified by This
|

|
||
|
|

Arguments:

This - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.

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
