Hi Julian,

I am afraid I have to disagree with you, for the reason that by including
the header file you introduce unnecessary coupling. Let me elaborate. If a
.c file does not need to know the contents of a struct, but it only needs to
know that a pointer to an opaque struct, then one should not provide the C
file with knowledge on the internals of the struct (hence not include the .h
file).

Fair enough. I guess I just don't like void pointers.

Well, what I mean is this: suppose you have a function that gets a pointer to a struct as one of its parameters. This function calls another function with this parameter:

void foo(struct *bar) {
        some_other_fnct(bar);
}

Then foo() simply passes the pointer on to some_other_fnct(), and foo() does not need to know about the members inside struct bar. So I am not talking about void pointers here as the alternative.

Bye, Roland.
