Answer 1

C atomics are not an Apple-specific thing, but defined by the C standard. Given that, you can find tonnes of info about them from non-Apple sources. This includes both the standard and various tutorials that explain that standard.

Note The C standard effectively

#include

d its atomic architecture from the C++ standard. A lot of the best info out there is for C++, with a simple mapping to get you to C.
