how to check file modification time?

[Guest 123]

I want to watch a file which it will be modified by another application,if this file has been modified then i'll open the file and read it.
i coudln't find any existed code on the internet to solve this problem,so i tried by myself,but i couldn't find the function that can read the date/time stamp of the file.
if you have any idea about preprogrammed code or about the function that check the date/time of the file please answer me as soon as possible.
thank you in advance.

This isn't something that C++ covers by itself. So, you'll have to
use some operating system dependent method. Here's a link
which could be helpful to you if you're on Windows machines:

If you're on a unix machine, sadly, I don't know the answer.

You can use stat on the filename on startup and run stat on it at specified intervals. The information returned by stat will give you the modification date/time. If you are using Windows, stat is called _stat.
