Vance, thanks a lot for the examples. I'm thinking of wrapping a C
block of memory in a binary, without copying it, to work on it in
Erlang. The copying bit is a stickler, I absolutely do not want to
copy, i.e. duplicate, the block of memory.
Any way of accomplishing that, using undocumented features perhaps?
