Mmmm... It seems I didn't explain myself very well, sorry. The real time
task is something like:
while (1) do
{
sentence1();
sentence2();
sentence3();
pthread_wait_np();
}
Imagine that the execution is in "sentence1" and other task suspends
this one with "pthread_suspend_np". Will this task stop right there or
it will execute "sentence1", "sentence2", "sentence3" and stop in
"pthread_wait_np"?. Many thanks.
