Mutex between 2 threads

[Nbird]

Should we use Mutex to prevent writing on same file / device by 2 or more threads?

 

Any alternate suggestion?

In general, yes a mutex is fine. use it to control access to the shared resource. If you are doing something more demanding (video for example) you might want to use a more sophisticated mechanism to minimize possibility of blocking etc.
