This corresponds to yyGLRStack. yystack is *the* instance, and
it's local
to yyparse(). For any function that needs a pointer to that yystack,
yystackp is the parameter name. For C, none of these are in the user
interface. Does this make sense?
I think that under C, you have implemented your own stacks, which
people are not expected to change, and therefore they need not be in
the user interface. Under C++, it is different.
So in order to keep multilingual similarity, that suggests just
naming it
"yystack", without a "p". Names with a "p" added should then be
reserved
for C implementation variables, but not in the interface.
I don't believe yystack is part of the interface.
Under C++, one would be able to choose stack, with at least two
standard
choices: std::vector, and std::deque.
I see. I need to study this thing some day.
A question that might coming up is how to sync the two C and C++
implementations. At least they should be easily readable for
comparison, for easy development. One canm think of ways of going
further, to autmate it, though that is alter question.
