Or how can it be avoided to access the same file by two different process?
I experienced a few (but painful) data loss due to this problem, and I'm
unable to solve the problem.
You can use the fpflock call (unit 'unix') to lock (parts of) a file.
But be aware that BOTH processes must use this mechanism;
File locking is optional on Linux.
Nothing prevents a third process from using the file without locks.
