EnumCalendarInfo (Windows CE 5.0)

Send Feedback

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

BOOLEnumCalendarInfo(CALINFO_ENUMPROClpCalInfoEnumProc, LCIDLocale, CALIDCalendar, CALTYPECalType);

The CALTYPE constants define particular pieces of calendar information. The following table shows CALTYPE constants that are mutually exclusive — that is, they cannot**be used in combination with each other in a function call.

Type Description
CAL_ICALINTVALUE An integer value indicating the calendar type of the alternate calendar.
CAL_IYEAROFFSETRANGE One or more null-terminated strings that specify the year offsets for each of the era ranges. The last string has an extra terminating null character.
CAL_SABBREVDAYNAME1 Abbreviated native name of the first day of the week.
CAL_SABBREVDAYNAME2 Abbreviated native name of the second day of the week.
CAL_SABBREVDAYNAME3 Abbreviated native name of the third day of the week.
CAL_SABBREVDAYNAME4 Abbreviated native name of the fourth day of the week.

CAL_SABBREVMONTHNAME1 Abbreviated native name of the first month of the year.
CAL_SABBREVMONTHNAME2 Abbreviated native name of the second month of the year.
CAL_SABBREVMONTHNAME3 Abbreviated native name of the third month of the year.

CAL_SABBREVMONTHNAME7 Abbreviated native name of the seventh month of the year.
CAL_SABBREVMONTHNAME8 Abbreviated native name of the eighth month of the year.
CAL_SABBREVMONTHNAME9 Abbreviated native name of the ninth month of the year.
CAL_SABBREVMONTHNAME10 Abbreviated native name of the tenth month of the year.
CAL_SABBREVMONTHNAME11 Abbreviated native name of the eleventh month of the year.
CAL_SABBREVMONTHNAME12 Abbreviated native name of the twelfth month of the year.
CAL_SABBREVMONTHNAME13 Abbreviated native name of the thirteenth month of the year, if it exists.
CAL_SCALNAME Native name of the alternate calendar.

CAL_SMONTHNAME13 Native name of the thirteenth month of the year, if it exists.
CAL_SSHORTDATE Short date formats for this calendar type.

If the native name for the day of the week or for a month is an empty string, that name is identical to the name given in the corresponding locale information and therefore is not duplicated here.

The CAL_IYEAROFFSETRANGE and CAL_SERASTRING values vary in format depending on the type of optional calendar. The following example shows the values for these types (for each supported alternate calendar type) along with the formula for how to use the CAL_IYEAROFFSETRANGE value to compute the correct year given the Gregorian current year value Y:

CAL_ICALINTVALUE = "1"
CAL_IYEAROFFSETRANGE = ""
CAL_SERASTRING = ""

CAL_ICALINTVALUE = "2"
CAL_IYEAROFFSETRANGE = ""
CAL_SERASTRING = ""

CAL_ICALINTVALUE = "3"
CAL_IYEAROFFSETRANGE = "1989\01926\01912\01868\0"
CAL_SERASTRING = "Ux337B\0Ux337C\0Ux337D\0Ux337E\0"
if (Y>=1989) { Y = (Y–1989)+1; } 
if (Y>=1926 && Y<1989) { Y = (Y–1926)+1; } 
if (Y>=1912 && Y<1926) { Y = (Y–1912)+1; }
if (Y>=1868 && Y<1912) { Y = (Y–1868)+1; } 
if (Y<1868) { Y = Y; } 

CAL_ICALINTVALUE = "4"
CAL_IYEAROFFSETRANGE = "1912\0"
CAL_SERASTRING = "Ux4E2D\0Ux83EF\0Ux6C11\0Ux570B\0"
if (Y>=1912) { Y = (Y–1912)+1; } 
if (Y<1912) { Y = Y; }

CAL_ICALINTVALUE = "5"
CAL_IYEAROFFSETRANGE = "2333\0"
CAL_SERASTRING = ""
Y = Y+2333;
