Check if a file is in use

I don't know on which platform you are running... But I guess you need to use the OS API.

If on Windows, maybe this helps:

I guess if both processes try to lock the file exclusively the CreateFileA method will return an error which is explained in the MSDN article.

Let me know, if that works for you!

Problem solved, thanx!
