I actually do not know how your rewrite could be better, though. /* GCC thinks socket()/connect() might fail to set errno */ return errno ? errno : EIO; If a compiler thinks errno may *not* be set, can 'errno' be reliably used to decide if it can be returned as-is or a fallback value EIO should be used, without triggering the same (incorrect) working in the first place?
