EnumCalendarInfo

The EnumCalendarInfo function enumerates calendar information for a specified locale. The CalType parameter specifies the type of calendar information to enumerate. The function returns the specified calendar information for all applicable calendars for the locale, or for a single requested calendar, depending on the value of the Calendar parameter.

The EnumCalendarInfo function enumerates the calendar information by calling an application-defined callback function. It passes the callback function a pointer to a string buffer containing the requested calendar information. This continues until either the last applicable calendar is found or the callback function returns FALSE.

BOOL EnumCalendarInfo(
  CALINFO_ENUMPROC lpCalInfoEnumProc, // pointer to enumeration callback function
  LCID Locale,                        // locale of interest
  CALID Calendar,                     // calendar whose information is of interest
  CALTYPE CalType                     // type of calendar information of interest
);
