[ODE] Passing NULL dBodyIDs to dJointAttach

Are there any adverse affects from passing NULL (zero) dBodyIDs to 
dJointAttach? I do this in my current collision callback, and I'm 
wondering if I should do null-checking myself.

void collision_function(...)
{
     ... blah blah blah...

     dJointAttach(
         dJointCreateContact(odeWorld, odeContactJointGroup, &contact),
	        dGeomGetBody(o1),
      	   dGeomGetBody(o2));

     ... blah blah blah...
}

Thanks for your help
