https://bugzilla.kernel.org/show_bug.cgi?id=217821 Bug ID: 217821 Summary: document that Linux' open(2) uses ENXIO in case of sockets, while POSIX mandates EOPNOTSUPP Product: Documentation Version: unspecified Hardware: All OS: Linux Status: NEW Severity: enhancement Priority: P3 Component: man-pages Assignee: documentation_man-pages@xxxxxxxxxxxxxxxxxxxx Reporter: calestyo@xxxxxxxxxxxx Regression: No Hey. It seems that under Linux, when using a socket file with the open(2) family of functions, the error is: > ENXIO The file is a UNIX domain socket. OTOH, POSIX specifies[0]: > [EOPNOTSUPP] > The path argument names a socket. Maybe it makes sense to document that? Possibly right at the ENXIO descripton and even additionally in the STANDARDS section? I could write a patch if you tell me which you like. Cheers, Chris.
