You said, ca_sg functions are not that useful. I thought they are the
correct way to implement a "caput and wait until processing has
completed". Isn't that correct? Is there an other way to do that?

As Ben has already pointed out, that functionality is implemented by
ca_put_callback(), not the ca_sg functions. Looking at it I can see
that the CA documentation doesn't really explain the rationale for sync
groups or emphasize the fundamental difference between ca_put() and
ca_put_callback() very well (and ca_put_callback() isn't even listed in
the function index). I've filed a bug report to ask Jeff to improve
these aspects of the documentation.
