Timestamps

[Ma3x323]

Hello,
Wondering how you can get a timestamp from a certain file. I need it to simulate the makemake utility which needs the timestamps for the files so it can recognize which ones have been modified.
Need it to be compatible in all OS platforms.

Thanks in advance -Feryl

see _getsystime in time.h Ion Filipski

Does that function gets the system time or the time the file was last modified. I also thought that each file would contain a time stamp somewhere and maybe parse it. But I don't where it is. -Feryl

I wasn't attentive. In windows you can use GetFileTime, is compatible with many file systems, but not very compatible with different Operating Systems. Put this question in Unix C++ forum. OS independent code you can make only in Java. Ion Filipski

OK. I am not a big windows programmer. Just in school still and most of my projects are command prompt/ dos based. So I am wondering what #include would be needed and how the function works. Maybe a little code?? Sorry to bother. Thanks a lot.

#include<windows.h>
......
FILETAME CreationTime, LastAccessTime, LastWriteTime;
BOOL x = GetFileTime(
hFile,&CreationTime,&LastAccessTime,&LastWriteTime);

If you want OS independence use the C runtime library.

This should work for UNIX, Windows, and DOS going back several revs.

#include <time.h>
#include <sys/types.h>
#include <sys/stat.h>

.

.
struct _stat s;

if ( 0 == _stat( &quot;c:\\somepath\\somefile.ext&quot;, &s ) ) {
/* the files's last modified time is in s.st_mtime */
}
else {
/* error - file probably doesn't exist */
}
