Hi All,

I was testing a CSD here and it seems that chnexport always fails if
hints are not given.  The relevant code looks to be:

 if (UNLIKELY(hints.min >= hints.max || hints.dflt < hints.min ||
                 hints.dflt > hints.max ||
                 (hints.behav == CSOUND_CONTROL_CHANNEL_EXP &&
                  ((hints.min * hints.max) <= FL(0.0))))) {
      return CSOUND_ERROR;
    }

With the default hints, hints.min = 0 and hints.max = 0, therefore the
first predicate will always fail.  Changing it to hints.min >
hints.max seems to fix it, and seems logical enough to me but I wanted
to verify.

Thanks!
steven

Very late reply, but just wanted to confirm this is a good solution.

Cheers,
