[ODE] Basic question about dBodyGetRotation() and 2D angles

I'm trying to use ODE for 2D and I've been reading the example posted
on the Pop Cap forums. I think my program ALMOST works but I'm having
a bit of trouble with the angles.
Here's what I'm doing:
const dReal* matrix;
matrix = dBodyGetRotation(myBody);
dReal angle = atan2(matrix, matrix);
What I want is the Z angle of rotation. I can't use Euler angles or
anything fancy. My 2D graphics engine uses (0, 0) for the top-left
corner and whatever you specify for the bottom right corner (eg. 800,
So can anybody help me out?
Thanks in advance!
