Windows function map?

Is there some sort of thing like a layout/plan of the windows api? A clear overview of which api depends on another? Or a website where they are linked in a hierarchical way (starting with the most depe开发者_如何学编程ndable, ending with the core function)

e.g Kerenel32.dll!CreateFile() -> ntdll.dll!ntCreateFIle() -> ntoskrnl32.exe!zwCreateFile()

I can link them all by hand with a dependency walker but it takes much time. So I was just wondering if something like this already existed.

I don't have the answer to your question, but I think an even more interesting road would be to read what Geoff Chappell has found out regarding the Windows Kernel and the Win32 API. I have not read those sections, but so far everything I've read on that website has filled me with wonder and awe at how thoroughly things can be analysed given a disciplined and talented investigator.

You can always take a look at ReactOS:

ReactOS® is a free, modern operating system based on the design of Windows® XP/2003. Written completely from scratch, it aims to follow the Windows-NT® architecture designed by Microsoft from the hardware level right through to the application level.

Simply search for whatever function in the documentation and look at its source. 99% of the time you can just pretend to be looking at the actual Windows source :) Very helpful when playing around with a debugger too.
