func FileOwner(fi os.FileInfo) (uid, gid, muid string)

FileOwner retrieves ownership information for a file. uid and gid are the owner and group of a file, respectively. muid is the uid of the user who last modified the file.

FileOwner will emply multiple strategies to get file ownership information. If fi or fi.Sys() implements any methods in the styx.OwnerInfo interface, they are used. Otherwise, FileOwner will attempt to retrieve ownership information from the host operating sytsem. If such information cannot be retrieved, FileOwner will fall back to DefaultUid and DefaultGid.
