EnumCalendarInfoEx

The EnumCalendarInfoEx 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 EnumCalendarInfoEx function enumerates the calendar information by calling an application defined–callback function. It passes the callback function a pointer to a buffer containing the requested calendar information and a calendar identifier (CALID). This continues until either the last applicable calendar is found or the callback function returns FALSE.

BOOL EnumCalendarInfoEx(
  CALINFO_ENUMPROCEX pCalInfoEnumProcEx, // callback function
  LCID Locale,                           // locale
  CALID Calendar,                        // calendar
  CALTYPE CalType                        // information type
);
