Hi

I have som problems creating a periodic posix thread. When I call 
pthread_make_periodic_np it returns 3 (ESRCH). I have created the 
following test:

void *thread()
{
   while(1)
   {
     pthread_wait_np(NULL);
     printf("Test\n");
   }
}

int main()
{
   pthread_t t;

   pthread_create(&t, NULL, thread, NULL);

   struct timespec start, period;
   clock_gettime(CLOCK_REALTIME, &start);
   period.tv_sec = 10;
   period.tv_nsec = 0;

   int error = pthread_make_periodic_np(t, &start, &period);
   printf("%i\n",error);

   if ( error == 0 )
     pthread_join(t, NULL);
}

Why does it fail?
