Retrieves a Unicode string that is the user readable name of the EFI 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.

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.
