InitializeLangVariable()

VOID InitializeLangVariable	(	IN CHAR16 *	LangName,
		IN CHAR8 *	SupportedLang,
		IN CHAR8 *	DefaultLang,
		IN BOOLEAN	Iso639Language
	)

Initialize Lang or PlatformLang variable, if Lang or PlatformLang variable is not found, or it has been set to an unsupported value(not one of platform supported language codes), set the default language code to it.

Parameters

LangName	Language name, L"Lang" or L"PlatformLang".
SupportedLang	Platform supported language codes.
DefaultLang	Default language code.
Iso639Language	A bool value to signify if the handler is operated on ISO639 or RFC4646, TRUE for L"Lang" LangName or FALSE for L"PlatformLang" LangName.

IsLangInSupportedLangCodes()

BOOLEAN IsLangInSupportedLangCodes	(	IN CHAR8 *	SupportedLang,
		IN CHAR8 *	Lang,
		IN BOOLEAN	Iso639Language
	)

Check if lang is in supported language codes according to language string.

This code is used to check if lang is in in supported language codes. It can handle RFC4646 and ISO639 language tags. In ISO639 language tags, take 3-characters as a delimitation to find matched string. In RFC4646 language tags, take semicolon as a delimitation to find matched string.

For example: SupportedLang = "engfraengfra" Iso639Language = TRUE Lang = "eng", the return value is "TRUE", or Lang = "chs", the return value is "FALSE". Another example: SupportedLang = "en;fr;en-US;fr-FR" Iso639Language = FALSE Lang = "en", the return value is "TRUE", or Lang = "zh", the return value is "FALSE".

Parameters

SupportedLang	Platform supported language codes.
Lang	Configured language.
Iso639Language	A bool value to signify if the handler is operated on ISO639 or RFC4646.

Return values

TRUE	lang is in supported language codes.
FALSE	lang is not in supported language codes.
