93 Retrieves a Unicode string that is the user readable name of the driver.
95 This function retrieves the user readable name of a driver in the form of a
96 Unicode string. If the driver specified by This has a user readable name in
97 the language specified by Language, then a pointer to the driver name is
98 returned in DriverName, and EFI_SUCCESS is returned. If the driver specified
99 by This does not support the language specified by Language,
100 then EFI_UNSUPPORTED is returned.
102 @param This[in] A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
103 EFI_COMPONENT_NAME_PROTOCOL instance.
105 @param Language[in] A pointer to a Null-terminated ASCII string
106 array indicating the language. This is the
107 language of the driver name that the caller is
108 requesting, and it must match one of the
109 languages specified in SupportedLanguages. The
110 number of languages supported by a driver is up
111 to the driver writer. Language is specified
112 in RFC 3066 or ISO 639-2 language code format.
114 @param DriverName[out] A pointer to the Unicode string to return.
115 This Unicode string is the name of the
116 driver specified by This in the language
117 specified by Language.

147 Language, then a pointer to the controller name is returned in ControllerName,
148 and EFI_SUCCESS is returned. If the driver specified by This is not currently
149 managing the controller specified by ControllerHandle and ChildHandle,

175 number of languages supported by a driver is up
176 to the driver writer. Language is specified in

181 controller specified by ControllerHandle and
182 ChildHandle in the language specified by
183 Language from the point of view of the driver
