Assuming vanilla AFS ... the absolute easiest way to check to see if a
directory entry is a mount point is stat() the directory.  If the inode
number of the directory is odd, it's a "real" directory.  If the inode
number is even, it's a mount point.

Determing the mount point NAME is more code from C; popen("fs lsm <X>")
might be the easist.  You won't have to do it that often once you figure
out what is and isn't a mountpoint, though.
