C doesn't have a stable ABI, most folks mistake the ABI from OS written in C, with an imaginary C ABI.

- flohofwoe 6mo agoOS ABIs are usually stable though ;) Finally someone getting it right though. C doesn't have any ABI per se, compilers need to implement whatever ABI a specific operating system defines (otherwise the language would be pretty useless since it couldn't call into operating system functions).
- cozzyd 6mo agoSure that's technically correct, but in practice it means I get a stable ABI :).
