NAME
date_from_tm - convert between tm struct and Windows DATE value
SYNOPSIS
#include <synce.h>
bool date_from_tm(struct tm *pTm, DATE *pDateOut);
bool date_to_tm(DATE dateIn, DWORD dwFlags, struct tm *pTm);
DESCRIPTION
The date_from_tm() function converts a tm struct into the Windows DATE
field pointed to by pDateOut. Only years after 1900 are converted. The
fields tm.tm_wday, tm.tm_yday and tm.tm_isdst are not used.
date_to_tm() does the reverse. It only fills the fields tm_sec, tm_min,
tm_hour, tm_year, tm_day, tm_mon. Dates before January 1st 1900 are not
supported. dwFlags should be 0, DATE_TIMEVALUEONLY to omit the date
information or DATE_DATEVALUEONLY to omit time information. Whereas the
tm.tm_year field usually holds the number of years since 1900, this
function provides the complete year.
RETURN VALUE
Both functions return FALSE on encountering an invalid value or year
earlier than 1900, or TRUE if successful.
