Our application has logging module. The module writes all the information to a file. The application is a multithreaded application where threads are writing data to an application.
Now our application is going to run on smp based systems. So file locking for processes, i am using the fcntl. Do I need to use thread locking for file. Do i need to use mutex for thread locking ?
Will there be a situation where two threads running on two different processors tries to write to the same logging file ? In that case how do i achive synchronization or it will be taken care by smp kernel itself ?
Thanks in Advance,
