GetFileTime
The GetFileTime function retrieves the date and time that a file was created, last accessed,
and last modified.
BOOL GetFileTime(
HANDLE hFile, // handle to the file
LPFILETIME lpCreationTime, // address of creation time
LPFILETIME lpLastAccessTime, // address of last access time
LPFILETIME lpLastWriteTime // address of last write time
);
Parameters
hFile
Handle to the files for which to get dates and times. The file handle must have been created
with GENERIC_READ access to the file.
lpCreationTime
Pointer to a FILETIME structure to receive the date and time the file was created. This parameter
can be NULL if the applicationdo
es not require this information.
lpLastAccessTime
Pointer to a FILETIME structure to receive the date and time the file was last accessed. The last
access time includes the last time the file was written to, read from, or, in the case of executable files, run. This parameter can be NULL if the application
does not require this information.
lpLastWriteTime
Pointer to a FILETIME structure to receive the date and time the file was last written to.
This parameter can be NULL if the applicationdo

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 FAT and NTFS file systems support the file creation, last access, and last write
time values.
Windows 95: The precision of the time for a file in a FAT file system is 2 seconds.
The time precision for files in other file systems, such as those connected through
a network depends on the file system but may also be limited by the remote device.
