volume serial number + volume label

[andrew clarke]

Hi,

How can I programmatically retrieve the "volume serial number" and
"volume label" of a removable disc in FreeBSD?  This is the same
information that's presented by issuing a "dir" command in Windows:

 Volume in drive D is FooBar
 Volume Serial Number is 58BB-96AA

This is for a small disk cataloguing program I'm writing in Python and
C++.

Thanks.

Regards
Andrew
