Hello! I wrote a POSIX application using Linux(2.4) & QNX. There are 2 threads with the following params : *T1 with SCHED_FIFO & priority == N *T2 with SCHED_FIFO & priority == N+1 with QNX everything runs perfect, but with Linux, it seems that priorities are not taken into account (T2 is preemted by T1). PS : With Linux I run the app with root privileges as required. Any idea? Thank you Vincent
