- throwaway27448 5mo agoThe ABI is not the issue.
- cozzyd 5mo agoIt's an issue if you want different software components to talk to each other without IPC.
- throwaway27448 5mo agoMost languages can interoperate with the C abi without commiting you to using the language itself. In fact I can't think of a single language that both produces software people actually use and doesn't interoperate with the c abi.
- pjmlp 5mo agoC doesn't have a stable ABI, most folks mistake the ABI from OS written in C, with an imaginary C ABI.
- throwaway27448 5mo agoEven then, arrays can be encoded and enforced on each side. It would be simpler to enforce this via the abi—but the abi itself does not open issues with array description and access
- flohofwoe 5mo 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 5mo agoSure that's technically correct, but in practice it means I get a stable ABI :).
