Just as a matter of information.... The seekdir/telldir interface was debated recently by the Austin Group. The Open Group wanted to include it as part of the XSI extension to 1003.1-200x; other people were strongly opposed to its inclusion. I believe the final decision was that it seekdir/telldir would not be included, because it is impossible to implement over certain filesystems (e.g., SGI's XFS, which uses a radically different data structure for directories). -GAWollman -- Garrett A.
