- Subject: [ECOS] cyg_scheduler_lock() understanding...
Hi,
I still search for the delay DSR and found it that the DSR will be
permitted due to a scheduler_lock. I quickly have some question while going
deeper into ecos.
Does the scheduler_lock also permits the thread switching? Or is it
possible that the scheduler switches to another thread while in lock mode?
If thread switching is permitted, how could the scheduler_lock be higher
than one if no dsr or isr calls scheduler_lock()?
Bye...
