After trying many different configurations,
I now seem to be making negative progress. So
I'm going back to the C code and getting my
brain out of Ada for a few moments... in case
this helps someone make sense of what I should
do, here's what the code looks like in C:

  typedef void* SRV_HANDLE;
  typedef void* RSLT_HANDLE;
  typedef void* CTX_HANDLE;


  SRV_HANDLE hand = 0;
  RSLT_HANDLE results;
  CTX_HANDLE ctx = 0;
  char name[255];
  double value = 0.0;

  status = InititalizeLibrary("config.txt", &hand);
  // omitting error checking here
  status = LookupResults(hand, "keystring", &results);
  // reset these after every lookup
  ctx = 0;
  name[0] = 0;
  status = GetNextVal(hand, results, &ctx, name, &value);
  // this call can be repeated to get a series of name/value
  // pairs. ctx is the handle to keep track of repeated
  // calls, and starts at the beginning when 0.

Clear as mud? I'm stumped, and sad that my Ada is so rusty.
