22 Retrieves a Unicode string that is the user readable name of the driver.
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.
31 @param This[in] A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
32 EFI_COMPONENT_NAME_PROTOCOL instance.
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
39 number of languages supported by a driver is up
40 to the driver writer. Language is specified
41 in RFC 4646 or ISO 639-2 language code format.
43 @param DriverName[out] A pointer to the Unicode string to return.
44 This Unicode string is the name of the
45 driver specified by This in the language
46 specified by Language.
48 @retval EFI_SUCCESS The Unicode string for the Driver specified by
49 This and the language specified by Language was
50 returned in DriverName.
52 @retval EFI_INVALID_PARAMETER Language is NULL.
54 @retval EFI_INVALID_PARAMETER DriverName is NULL.
