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

52 @param This A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
53 EFI_COMPONENT_NAME_PROTOCOL instance.
54 @param Language A pointer to a Null-terminated ASCII string
55 array indicating the language. This is the
56 language of the driver name that the caller is
57 requesting, and it must match one of the
58 languages specified in SupportedLanguages. The
59 number of languages supported by a driver is up
60 to the driver writer. Language is specified
61 in RFC 4646 or ISO 639-2 language code format.
62 @param DriverName A pointer to the Unicode string to return.
63 This Unicode string is the name of the
64 driver specified by This in the language
65 specified by Language.

67 @retval EFI_SUCCESS The Unicode string for the Driver specified by
68 This and the language specified by Language was
69 returned in DriverName.
70 @retval EFI_INVALID_PARAMETER Language is NULL.
71 @retval EFI_INVALID_PARAMETER DriverName is NULL.
