Hello.
I'm quite new to this "d"-thing, but it seems very interesting and i think i
will use it, if i can clear a few things up. I have, based on the reading i
have done, made the following assumptions, please correct me where i'm
wrong. 

1. D can link to C libraries. The standard c library have been wrapped(all
functions redeclared with "extern (C) ...") in std.c.xxx-modules, so we can
use them easily. 

2. I cannot use functions from a c library unless i have declared them as
extern (C) in my D source code. Structures in the c library that i want to
use in my code have to be declared in my D code.

Correct.

That's correct, too.
How should the compiler know about the functions and structures if you 
don't do that?

Both assumptions are correct.
