site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com I have a server process running as root that needs to create a file on behalf of a user. I want the file creation operation to be subjected to the requesting user's permissions, so I'm using seteuid(). However, this is not enough, since additional permissions may be given to the user's group, so I also call setegid(). This isn't enough either, since the user may belong to several groups, so I call setgroups() as well. Questions: 1. Given the user's uid, what's the best way to determine the user's gid and groups list? 2. Am I forgetting something?
