Easy. Read the source and do:
pthread_self()->period= new_period_in_ns;
You may also wish to modify pthread_self()->resume_time before entering
ptrhread_wait_np().
BTW: Feature request:
Functions which:
1. Change the period starting from THIS, not next wait (both ->period and
->resume_time have to be changed).
pthread_self()->resume_time = ...->resume_time - ...->period + new_period;
pthread_self()->period = new_period;
2. Delay the thread by given number of ns.
pthread_self()->resume_time = gethrtime() + t_ns;
pthread_wait_np();
3. Delay the thread by a given number of ns from the last scheduled wake-up
pthread_self()->resume_time = ...->resume_time - ...->period + delay;
pthread_wait_np();
4. Wait until specified time (easiest)
pthread_self()->resume_time = time_until;
pthread_wait_np();
Is any from above already implemented? Since these functions are simple, may
be they can be provided as simple macros?
