EnumDateFormats info  Overview  Group

The EnumDateFormats function enumerates the long or short date formats that are available for a specified locale, including date formats for any alternate calendars. The value of the dwFlags parameter determines whether the long or short date formats are enumerated. The function enumerates the date formats by passing date format string pointers, one at a time, to the specified application-defined callback function. This continues until the last date format is found or the callback function returns FALSE.

BOOL EnumDateFormats(

    DATEFMT_ENUMPROC lpDateFmtEnumProc,

// pointer to enumeration callback function

    LCID Locale,

// locale whose date formats are of interest

    DWORD dwFlags
