int I18nCurrentLanguage | ( | void | ) |
Returns the index of the current language.
This number stays the same for any given language while the program is running, but may be different when the program is run again (for instance because a locale has been added or removed). The default locale ("en_US") always has a zero index.

void I18nInitialize | ( | const char * | LocaleDir = NULL | ) |
Detects all available locales and loads the language names and codes.
If LocaleDir is given, it must point to a static string that lives for the entire lifetime of the program.

bool I18nIsPreferredLanguage | ( | int * | PreferredLanguages, |
const char * | LanguageCode, | ||
int & | OldPreference, | ||
int * | Position = NULL |
||
) |
Checks the given LanguageCode (which may be something like "eng" or "eng+deu") against the PreferredLanguages and returns true if one is found that has an index smaller than OldPreference (which should be initialized to -1 before the first call to this function in a sequence of checks).
If LanguageCode is not any of the PreferredLanguages, and OldPreference is less than zero, OldPreference will be set to a value higher than the highest language index. If Position is given, it will return 0 if this was a single language code (like "eng"), 1 if it was the first of two language codes (like "eng" out of "eng+deu") and 2 if it was the second one (like "deu" out of ""eng+deu").

const char* I18nLanguageCode | ( | int | Language | ) |
Returns the three letter language code of the given Language (which is an index as returned by I18nCurrentLanguage()).
If Language is outside the range of available languages, NULL is returned. The returned string may consist of several alternative three letter language codes, separated by commas (as in "deu,ger").

int I18nLanguageIndex | ( | const char * | Code | ) |
Returns the index of the language with the given three letter language Code.
If no suitable language is found, -1 is returned.

const cStringList* I18nLanguages | ( | void | ) |
Returns the list of available languages.
Values returned by I18nCurrentLanguage() are indexes into this list. Only the first I18nNumLanguagesWithLocale() entries in this list have an actual locale installed. The rest are just dummy entries to allow having three letter language codes for other languages that have no actual locale on this system.

const char* I18nLocale | ( | int | Language | ) |
Returns the locale code of the given Language (which is an index as returned by I18nCurrentLanguage()).
If Language is outside the range of available languages, NULL is returned.

If no normalized language code can be found, the given Code is returned. Make sure at most 3 characters are copied when using it!
