Hi list, I do not represent any implementations, I ask this merely as an application developer who has asked around.
Can .sun_path be a flexible array member? The standard says it has unspecified size, but also normatively says "The sockaddr_storage structure defined in <sys/socket.h> shall be large enough to accommodate a sockaddr_un structure." This doesn't clear things up unless we have a notion of whether "size of a structure" includes its flexible array member, and even if that is true, whether including a flexible array member on sockaddr_storage (albeit one which a portable application wouldn't know how to access) would satisfy this. The example for bind() uses sizeof() on .sun_path, suggesting the answer to my question is "no," but examples aren't normative. If the standard could say whether this is permitted more clearly, that would make me happy. Thanks for your attention to my inquiry, John
