dtrace discuss - Jan 2006 - getting all open files

I know I can check the path of a file being opened with arg0 of the open
function but is there a way to list all open files of a process when a
read:entry probe is fired from it?

There''s no simple way to perform that sort of iteration with DTrace,
but
you could invoke the pfiles(1) command in user-land like this:

syscall::read:entry
/execname == "foo"/
{
	stop();
	system("pfiles %d", pid);
	system("prun %d", pid);
}

You''ll obviously need destructive actions enabled to get this to work
so
be careful -- you could get into trouble if, for example, you tried to
stop the dtrace command itself.
