Hi all,

Sorry for the necro of this thread but I am still interested in this. Are you saying that by disabling interrupts my thread will not be preempted? even if a thread with higher priority requires cpu?

I didn’t say it, but yes that is correct. In a single processor system, if you turn off interrupts, you cannot be pre-empted. Without external interrupts, processors execute code linearly. Other than a peripheral triggering a hardware interrupt, only the timer would cause a pre-emption and/or rescheduling. The only exception I can think of to this would be an internal interrupt caused by something like executing a bad instruction or a segmentation violation.

What I am really looking for is an way to make a function run without being preempted.

Btw, I only use between 10

Thanks allot for your reply. I will ponder this.

David
