I have to check whether 2 directories are on the same filesystem. I built a test case on a Linux debian woody (3.0) with kernel 2.4.28 with 1 directory on a local drive, the other on an NFS-mounted tree.

I tried statfs and statvfs, both reply that f_fsid is zero for both directories. I also tried plain stat, here st_dev is not zero, but still it is the same (very large number) for both.

I suppose parsing /proc/mounts would be a way, but that doesnt appeal at all!

Now I'm out of ideas. Suggestions? TIA.
Odd.
Verify your code with the stat command atleast.
$ stat /proc
$ stat /
$ stat /your/nfs/directory

The line saying "Device: ... " are different for me.

Good advice. Have installed stat, it gives different "Device" for local and NFS directory, proving that *some* system call works. I'll have a look at the source code to see what "Device" is exactly. Thanks.
