Actually, no, that's perfectly fine. You an also get the thread's TID and use sched_setscheduler(2). > So, my question.

Sorry, the API in question is reserved for root. Since Qt applications are almost always run as regular users, it would see very little use. Therefore, I don't think we'll add it. For the few users who need it and know what they're doing, like you, you can use the pthreads or Linux-specific API. You're probably doing enough code reviews and static analyses anyway for your application running as root that this is not an undue burden. -- Thiago Macieira - thiago.macieira (AT) intel.com Principal Engineer - Intel Platform & System Engineering
