digitalmars.D.learn - How do I use my c/c++ libraries in D?

'import std.c.stdio', where does the compiler look for this file)
- Does the D compiler use C header files, or header files which are converted
to D?

I mainly want to use the Windows / DirectX API in D, as well as some other
libraries.

I suppose this question has been asked many times, but I couldn't find it on
the forums. (neither did I find my answer somewhere else on the web)

Headers converted to D. The ctod program from the digital mars site will 
  do an automatic conversion for you. You also need the coffimplib 
program to convert the .lib files from Microsoft/COFF format into OMF 
format.

Look on www.dsource.org in the 'bindings' project, several have already 
been converted.

The standard C library is included in the runtime, see 
dmd\src\phobos\std\c for declarations.

Headers files which are converted to D. See 
http://www.digitalmars.com/d/htomodule.html for converting header files 
to D. There is also a tool which can do a lot automatically:

Take a look at www.dsource.org if you have not done already, chance is 
that there is already a binding. The wiki4d may also have more links to 
bindings. A set of bindings for win32 is here: 
http://www.prowiki.org/wiki4d/wiki.cgi?WindowsAPI

I have seen some directx bindings somewhere, but don't remember where 
they are.

D doesn't compile C/C++ files. std.c.stdio is actually a D import module.

Packages such as std.c generally map to a directory structure. In this case, 
the path is dmd\src\phobos\std\c\stdio.d. The compiler also reads sc.ini in 
the dmd\bin folder to determine where to look for import libraries - for 
instance, "-I..\..\src\phobos".

The latter. There's a utility called htod 
http://www.digitalmars.com/d/htod.html that attempts to generate a D module 
from a C header.

The WindowsAPI project on DSource has translations of many of the SDK 
headers, including DirectX. 
http://www.dsource.org/projects/bindings/browser/trunk/win32

Check out DSource for other libraries that have been ported to D. If you 
don't find what you need there, there's the aforementioned htod. But it's 
not that difficult to translate C headers by hand - just tedious... Issues 
to watch out for include macro expansions and bit fields.
