Note that EFTYPE and EEXIST are not listed in specificat= ion for bind(2), thus this allows us consider suggested functionality to be an extension over specification. https://pubs.opengroup.org/onlinepubs/9699919799/functions/bind.html May I ask you to do two things: 1) Check how these edge cases work on other popular POSIX OSes, at least Li= nux and Mac OS X. If they also do something smart here, we probably should stay compatible with them. 2) If step 1) doesn't uncover need for any additions, please document in bind(2) cross referencing to unix(4). --=20 You are receiving this mail because: You are the assignee for the bug.=
