"Nah.  The best idea is to start using Ada95 and use the _standard_ out
 of the box interoperability of Interfaces.C.Strings which does all this
 (and more)."
 

Interfaces.C.Strings lets me create a copy of the Ada string, and pass
a pointer to that copy. The callback can then make an Ada string from this
copy. This all seems rather expensive, as well as only being by value.

Is there any way to pass the string _by reference_ in a manner that is
reasonably portable (even with the use of unchecked conversion). I'm 
really looking for a way of getting a pointer to the string somehow
that is compatable with size of C pointers.
