If you don't need file storage, sounds like all you need is something 
equivalent to perl's hashes. Some options:

1. libperl and manipulate it's hashes through their C interface
2. A quick wrapper around c++ STL's Map (actually tree based, which offers O(n 
log n) access rather than amortized (critical word there) 0(1) performance 
which you could get if your c++ library supports hash_map

I'd probably do the latter since it avoids the overhead of creating a perl 
interpeter, but you may find this a preferred approach.
