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

48 This function retrieves the user readable name of a driver in the form of a
49 Unicode string. If the driver specified by This has a user readable name in
50 the language specified by Language, then a pointer to the driver name is
51 returned in DriverName, and EFI_SUCCESS is returned. If the driver specified
52 by This does not support the language specified by Language,
53 then EFI_UNSUPPORTED is returned.

55 @param This[in] A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
56 EFI_COMPONENT_NAME_PROTOCOL instance.

59 array indicating the language. This is the
60 language of the driver name that the caller is
61 requesting, and it must match one of the
62 languages specified in SupportedLanguages. The
63 number of languages supported by a driver is up
64 to the driver writer. Language is specified
65 in RFC 4646 or ISO 639-2 language code format.
