Getting a list of open files, the smart way?

["Diego Escalante Urrelo" <diegoe gnome org>]

Hi,

I have made a quite simple patch for bug 528559[0], it makes the quite
useless "drive is being used" dialog into a list of applications using
such drive[1].

I'm using a little hack with lsof, but it's not really reliable, like
when process names are too long. I checked libgtop quickly but the
lack of documentation didn't help.

So, I'm writing to get some clues about this, any advice? My main
problem is to do something like "tell me which files in device $d are
in use, and tell me the executable for the process using such file"

thanks everyone,

Diego
