Hi I'm porting an application from another realtime-os to Linux. This application makes use of intLock() from time to time. I still need the the application to be compilable on both Linux and my old os, so I need a portabel intLock() I have tried the following approach: When a thread needs to do intLock, I boost the thread-pri to max, and when the thread does intUnLock() I set the thread-pri back. This woorks quite ok, but by using this approach, I will also lock other threads in other applications running on Linux. What I really need is a way of blocking all other threads in my application, without affecting other applications. I know I can use mutex'es and semaphores, but that will require a major rewriting of the application, and that is somthing I dont want to do. Can someone come up with an idea how this is done best?
