devLib, locationProbe routine |

Am I right in thinking that the routine locationProbe in devlib returns
SUCCESS to indicate that the given address does *not* respond to VME accesses of
any size? I presume the aim here is to indicate that this area of the memory
map is currently not used.
Should I be using this in my driver to check that a board is present? The older
drivers use vxMemProbe, which returns OK if something responds. It seems wrong
to expect an error code (S_dev_addressOverlap) as the status return indicating
success (ie board found), which is what I would have to do if I used the
locationProbe routine.
Are there plans to modify the existing drivers to use the devLib facilities?
