Link to comment

can you tell me from which source this comes?

Honestly, I can't remember. I was just searching the web sometime ago, and I came across it and found it useful.

A fair amount of these aren't functions, but definitions for constant values as well as structures. Most of these are defined in the Windows driver development kit (WDK) which you can download from the Microsoft Connect site for free. A lot of these are also documented on MSDN here:

You can obtain the WDK here:
