https://bugzilla.kernel.org/show_bug.cgi?id=214171 Bug ID: 214171 Summary: I am not sure why the definition of EAI_SYSTEM, from getaddrinfo, was changed from POSIX Product: Documentation Version: unspecified Hardware: All OS: Linux Status: NEW Severity: normal Priority: P1 Component: man-pages Assignee: documentation_man-pages@xxxxxxxxxxxxxxxxxxxx Reporter: christian.morales.vega@xxxxxxxxx Regression: No https://man7.org/linux/man-pages/man3/freeaddrinfo.3p.html says: "[EAI_SYSTEM] A system error occurred; the error code can be found in errno." Which makes a lot of sense. The function can fall because of name-resolution specific problem (EAI_NODATA). But otherwise it must be a plain old generic error that can be expressed with errno, so you should look in errno. It's not explicitly said. But IMHO it's clear that it would be a bug to return EAI_SYSTEM without setting errno/setting errno to zero. But then https://man7.org/linux/man-pages/man3/getaddrinfo.3.html replaces it with: "EAI_SYSTEM Other system error, check errno for details." Which, I'm not a native speaker, but it seems to me to leave returning EAI_SYSTEM and setting errno to 0 more open to interpretation. You can argue that in such a case errno == 0 simply means "no details". -- You may reply to this email to add a comment.
