STL containers are easier to use, harder to misuse and take care of memory allocations. Wouldn't you say that's a benefit? If I wrote an algorithm in C++, I'd rather pass it a const std::vector<double>& than a const double * and a length. That said, I prefer C for simple extension modules which just wrap something. Less dependencies for the person who builds it, more people who understand it well enough to change it. /Jorgen -- // Jorgen Grahn <grahn@ Ph'nglui mglw'nafh Cthulhu \X/ snipabacken.dyndns.org> R'lyeh wgah'nagl fhtagn! -- http://mail.python.org/mailman/listinfo/python-list
