This collection of Native API header files has been maintained since 2009 for the Process Hacker project, and is the most up-to-date set of Native API definitions that we know of. We have gathered these definitions from official Microsoft header files and symbol files, as well as a lot of reverse engineering and guessing. See phnt.h for more information.
First make sure that your program is using the latest Windows SDK.
These header files are designed to be used by user-mode programs. Instead of #include <windows.h>, place
#include <phnt_windows.h>
#include <phnt.h>
at the top of your program. The first line provides access to the Win32 API as well as the NTSTATUS values. The second line provides access to the entire Native API.
Here is the copyright header which is removed for making amalgamated header.
