FileTimeToDosDateTime
The FileTimeToDosDateTime function converts a 64-bit file time to MS-DOS date and time values.
BOOL FileTimeToDosDateTime(
CONST FILETIME *lpFileTime,
| // pointer to 64-bit file time
| LPWORD lpFatDate,
| // pointer to variable for MS-DOS date
| LPWORD lpFatTime
| // pointer to variable for MS-DOS time
| );
|
|
Parameters
lpFileTime
Points to a FILETIME structure containing the 64-bit file time to convert to MS-DOS date and time
format. The FILETIME structure has the following form:
typedef struct _FILETIME { // ft
DWORD dwLowDateTime;
DWORD dwHighDateTime;
} FILETIME;
lpFatDate
Points to a variable to receive the MS-DOS date. The date is a packed 16-bit
value with the following format:
Bits
| Contents
| 0 4
| Day of the month (131)
| 58
| Month (1 = January, 2 = February, etc.)
| 915
| Year offset from 1980 (add 1980 to get actual year)
|
lpFatTime
Points to a variable to receive the MS-DOS time. The time is a packed 16-bit
value with the following format:
Bits
| Contents
| 04
| Second divided by 2
| 510
| Minute (059)
| 1115
| Hour (023 on a 24-hour clock)
|
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks
The MS-DOS date format can represent only dates between 1/1/1980 and
12/31/2107; this conversion fails if the input file time is outside this range.
