LinuxQuestions.org - thread priority

Hello,

I have been trying to start a thread with a high priority. When I do set it to a higher priority then the thread doesn't seem to execute. When I just run the thread with out passing it an attribute it works just fine.

Here is my code:

Code:

pthread_attr_t attr;

sched_param schedparam;

schedparam.sched_priority = 2;

pthread_attr_init(&attr);

pthread_attr_setinheritsched(&attr, PTHREAD_EXPLICIT_SCHED);

pthread_attr_setschedpolicy(&attr, SCHED_RR);

pthread_attr_setschedparam(&attr, &schedparam);



dasToTape->Start(NULL, &attr);

And here is the start function where I start the thread.

Code:

bool CWorkerThread::Start(void *pArg, pthread_attr_t *threadAttr)

{

        int rc;

        

        pthread_t thread;

        m_UserData= pArg;

        m_Shutdown= false;

        rc= pthread_create(&thread, threadAttr,  m_pThreadFunc, this);

        if(rc){

                cout << "thread creation failed" <<endl;

        }

        return 1;

}

Thanks
