|| Lyrics: XFSPerm - permissions for filesystem objects
||
|| The permissions are stored as string in format :
||
|| rwxrwxrwx[ user[:group[:other]]]
|| oooggguuu
||
|| Where first mandatary part is standard unix permissions string,
|| and first three characters are read-write-execute permitions for
|| others, second three characters are read-write-execute permissions
|| for group, and third three characters are read-write-execute
|| permissions for user. The rest of a string is a triplet for
|| of names for 'user', 'group' and 'other' ( which is for windows )
||
|| BTW that primitive is storeing data in char format, no gid or uid
|| because it should work well on different platforms. The final
|| transformation to native format will be implemented on each
|| platform.
||
|| So, righot now there is XFSPerm structure, which contains three
|| XFSAuth structures which represents user/group/other
||
