AutoRTFM is designed to make it easy to take existing C++ codeeven if it was never designed to have any transactional semanticsand make it transactional just by using an alternate compiler. For details, see `Engine/Source/Runtime/AutoRTFM/Documentation/README.md_. The C API exists for a few reasons:

• It makes linking easy. AutoRTFM has to deal with a weird kind of linking where the compiler directly emits calls to functions with a given name. It's easiest to do that in llvm if the functions have C linkage and C ABI.
• It makes testing easy. Even seemingly simple C++ code introduces pitfalls for AutoRTFM. So very focused tests work best when written in C.
• It makes compiler optimizations much easier as there is no mangling to consider when looking for functions in the runtime we can optimize.

We use snake_case for C API surface area to make it easy to distinguish.

The C API should not be used directly - it is here purely as an implementation detail.
