dtrace discuss - Nov 2010 - fileinfo structures returns no information

I can not get any information out of the fileinfo structure. A simple program
that should give me the io fileinformation always returns <none>

#pragma D option quiet
io:::start
{
   printf ("%5d %4d %4d %30s %30s\n", args[0]->b_bcount,
           args[1]->dev_major, args[1]->dev_minor,
           args[1]->dev_pathname, args[2]->fi_pathname);
}


 4096   83   18 /devices/pci at 0,0/pci1558,860 at 1f,2/disk at 0,0:s           
<none>

Hey Mike:

Are you on trying this on a ZFS file system? See discussion here for a possible
solution.

Thanks Angelo

Not great but it is a work around.
