[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...

         dJointCreateContact(odeWorld, odeContactJointGroup, &contact),

     ... blah blah blah...

Thanks for your help
