* File: LocaleMgr.h
*
* Release: Palm OS SDK 4.0 (63220)
*
* Description:
* Public header for routines that support locales (information specific
* to locales and regions).
*
* History:
* 04/28/00 CS Created by Chris Schneider.
* 05/16/00 CS LmCountryType/LmLanguageType are now back to
* CountryType/LanguageType.
* 05/31/00 CS Moved country and language codes to new Locale.h and removed
* kLanguageFirst, etc.
* 06/06/00 kwk Made _LmLocaleType's language & country fields be UInt16's,
* so that it's binary compatible with OmLocaleType.
* 07/28/00 CS Replaced lmChoiceMinutesWestOfGMT & lmChoiceDaylightSavings
* selectors with lmChoiceTimeZone.
* 08/08/00 CS Renamed LmGetLocaleSetting's <iMaxSize> parameter <iValueSize>
* to reflect the fact that the routine now checks to make sure
* that <oValue> is the correct size for all fixed-size settings.
* 09/29/00 CS Made iLocale parm of LmLocaleToIndex const.
* 11/17/00 CS Removed support for lmChoiceLanguage & lmChoiceCountry,
* since these guys were returning UInt8's, which probably
* won't cut it at some point in the future. Callers can use
* lmChoiceLocale, which returns an LmLocaleType struct that
* places the country and language into UInt16 fields.
* CS Defined lmAnyCountry & lmAnyLanguage, which can now be passed
* in LmLocaleToIndex's iLocale parameter (as wildcards).
*
