Probably true. But also, if you're talking about a const pointer to a

whit whether the pointer itself is const or not. What matters is whether
what's being pointed to is const or not. So, if you have a function which
takes a const pointer to a non-const value, then that's essentially
identical
to one that takes a non-const pointer to a non-const value as far as the
declarations go - and for declaring extern(C) functions for use in D,
that's
generally all you care about.

Ok I see, thanks. Is that true for fields in structs and global
variables as well?
Yes. const pointer in c++ is some times used as short hand for saying
that the pointer is not an array. i.e. you don't intend to increment the
pointer or index through it.
