How to obtain the FAT serial number form a volume

All,

I would like to retrieve the FAT serial number from a volume mounted on Mac OS X  from a C program.  Here is how one can do it from the command line.

dd if=/dev/disk4s1 skip=67 bs=1 count=4 | hexdump -v -e '1/1 "X" " "'

I have not found how to do this with the CoreFoundation classes.  I also need to find this information out as a regular user not a privileged user or root.

If anybody can point me in the right direction I would appreciate it.

Thanks,
Chris
