Re: Pointer function parameter

[Marin David Condic <mcondic.nospam@acm.org>]

While there are a lot of uses for access types, what needs to be carefully
explained to the C programmer approaching Ada is that in Ada you need
access/address a WHOLE*LOT*LESS than you do in C. C programmers will typically
start trying to write Ada code with C semantics and instead of "in out"
parameters, will start passing 'Address or 'Access of everything to
everything. I've seen it done. Its not pretty. It would be instructive to the
C programmer approaching Ada to observe very vigorously that while Ada has the
means to get pointers to everything, that doesn't mean one should do so with
the same regularity one might in C.
