WebApr 11, 2024 · An example of a critical region is a preempting interrupt handler (an IRQ). A use for this function is to schedule a callback from a preempting IRQ. Such an IRQ puts restrictions on the code that runs in the IRQ (for example the heap may be locked) and scheduling a function to call later will lift those restrictions.
