Read up on pack() and unpack(). We use it to get C++ structures from a dll
and throw them into a hash ref and vice versa.
The basic concept would be for your dll or whatever to pass a pointer to
your perl script. Your perl script would then unpack() it as a long into a
variable. For perl, that's the same thing as a string which happens to be
a number. If you know how much memory each of your members of your
structure takes up, you can then (probably using another dll) get back into
memory and read off the memory piece by piece. Convoluted? Definitely --
we have way too much time on our hands :)
