22 Retrieves a Unicode string that is the user readable name of the driver.
23
24 This function retrieves the user readable name of a driver in the form of a
25 Unicode string. If the driver specified by This has a user readable name in
26 the language specified by Language, then a pointer to the driver name is
27 returned in DriverName, and EFI_SUCCESS is returned. If the driver specified
28 by This does not support the language specified by Language,
29 then EFI_UNSUPPORTED is returned.

34 @param Language[in] A pointer to a Null-terminated ASCII string
35 array indicating the language. This is the
36 language of the driver name that the caller is
37 requesting, and it must match one of the
38 languages specified in SupportedLanguages. The

40 to the driver writer. Language is specified
41 in RFC 4646 or ISO 639-2 language code format.
