EnumCalendarInfoExEx function

Enumerates calendar information for a locale specified by name.

Note  The application should call this function in preference to EnumCalendarInfo or EnumCalendarInfoEx if designed to run only on Windows Vista and later.

Note  This function can enumerate data that changes between releases, for example, due to a custom locale. If your application must persist or transmit data, see Using Persistent Locale Data.

Syntax

BOOL EnumCalendarInfoExEx(
  _In_      CALINFO_ENUMPROCEXEX pCalInfoEnumProcExEx,
  _In_opt_  LPCWSTR lpLocaleName,
  _In_      CALID Calendar,
  _In_opt_  LPCWSTR lpReserved,
  _In_      CALTYPE CalType,
  _In_      LPARAM lParam
);

Parameters

pCalInfoEnumProcExEx [in]

Pointer to an application-defined callback function. For more information, see EnumCalendarInfoProcExEx.

lpLocaleName [in, optional]

Pointer to a locale name, or one of the following predefined values.

• LOCALE_NAME_INVARIANT
• LOCALE_NAME_SYSTEM_DEFAULT
• LOCALE_NAME_USER_DEFAULT

Calendar [in]

Calendar identifier that specifies the calendar for which information is requested. Note that this identifier can be ENUM_ALL_CALENDARS, to enumerate all calendars that are associated with the locale.

lpReserved [in, optional]

Reserved; must be NULL.

CalType [in]

Type of calendar information. For more information, see Calendar Type Information. Only one calendar type can be specified per call to this function, except where noted.

lParam [in]

Application-provided parameter to pass to the callback function. This value is especially useful for multi-threaded applications.

Return value

Returns a nonzero value if successful, or 0 otherwise. To get extended error information, the application can call GetLastError, which can return one of the following error codes:

• ERROR_INVALID_FLAGS. The values supplied for flags were not valid.
• ERROR_INVALID_PARAMETER. Any of the parameter values was invalid.

Remarks

This function enumerates calendar information for all applicable calendars for the specified locale, or for a single requested calendar, depending on the value of the Calendar parameter. The function enumerates the calendar information by calling the specified application-defined callback function. It passes the callback function a pointer to a buffer containing the requested calendar information, a calendar identifier, and an application-defined parameter that is useful for multi-threaded applications. This process continues until EnumCalendarInfoExEx finds the last applicable calendar or the callback function returns FALSE.

Beginning in Windows 8: If your app passes language tags to this function from the Windows.Globalization namespace, it must first convert the tags by calling ResolveLocaleName.
