I don't forget I discovered specific varieties inside the C language referred to as atomic kinds, but we have never examined them.
of multitasking. The CPU scheduler can (and does) interrupt a approach at any level in its execution - even in mid perform contact. So for steps like updating shared counter variables wherever two processes could attempt to update the variable concurrently, they need to be executed 'atomically', i.
