[ECOS] How to "atomize" the end of a thread...

[Fabrice Gautier <Fabrice_Gautier at sdesigns dot com>]

Hi,

Let's say i have a thread, past a certain point in this thread I want to
lock the scheduler so that the thread will go to the end uninterrupted (I
want to atomize the last few lines of this thread). 

I don't want to do :
void thread1 ( int arg)
{
  ...
  cyg_sched_lock();
  atomic_function();
  cyg_sched_unlock();
} 

because I really want the thread to really return end before any other do
anything.

What happen if I do that with 

void thread1 ( int arg)
{
  ...
  cyg_sched_lock();
  atomic_function();
} 
 ?

You may have guessed that i'm trying to do a very bad thing. In this case i
want to free the stack used by the thread at the end of the thread, and this
would go bad if  someone were reusing this memory before the last function
returned and the thread was deleted from the scheduler.
