That's a good idea. The frontend framework should be independent of the used
hardware (CAMAC or VME or whatever). I event went further and removed the HAVE_CAMAC
completely. This means that people have to add the call to register_cnaf_callback()
explicitly into the frontend user init routine. I think this inconvenience is not a
big deal because even before that people had to add the cnaf_callback.c file
explicitely into their Makefile. So they have to be aware of that change, and then
it's not a big deal to modify the init routine as well. But this way we have mfe.c
completely independen of the DAQ hardware which is how it should be.
To make things a bit easier, I modified the midas\examples\experiment\fronted.c to
contain this call, so people should be guided by that. I also added cnaf_callback.c
to the Makefile of the example frontend.
