Having been bitten one more time by the use of -d to pass the
hypervisor URI instead of -c (confusion coming from CVS using
-d to specify the root), I suggest to drop atoi and use the
function with checking and error out with proper explanation instead
of silently failing !

Hear hear - atoi() is inherently stupid. There's a 'make syntax-check'
that we could turn on to prohibit all use of atoi(), but I don't know if
the code base is ready for that, so I'll save it for another patch on
another day.

Any reason you are still requiring decimal, or would it make more sense
to branch out and s/10/0/ in order to also accept hex?
At any rate, ACK to the patch.

let's try to clean this up after 0.8.3

the other use in virsh was also expecting decimal, I guess for a debug
level it's not a big deal to stick to decimal :-)
At any rate, ACK to the patch.
Okay, pushed :-) thanks !

Yeah, agreed. There aren't a huge number of uses of atoi() in the codebase,
but there are enough to require a bit of churn. Best left until after the
release.

Serves me right for not noticing this; gcc complained that the printf
string doesn't match the number of arguments.

Or, better yet:

since arg is not a string to be printed with %s.

urgh ... I'm blind !
I commited too fast, 2 commits then !
