     26   Retrieves a Unicode string that is the user readable name of the driver.
     27 
     28   This function retrieves the user readable name of a driver in the form of a
     29   Unicode string. If the driver specified by This has a user readable name in
     30   the language specified by Language, then a pointer to the driver name is
     31   returned in DriverName, and EFI_SUCCESS is returned. If the driver specified
     32   by This does not support the language specified by Language,
     33   then EFI_UNSUPPORTED is returned.

     41                                 requesting, and it must match one of the
     42                                 languages specified in SupportedLanguages. The
     43                                 number of languages supported by a driver is up

     45                                 in RFC 4646 or ISO 639-2 language code format.

     54                                 returned in DriverName.
