Wintexports

Wintexports (Windows INTernal EXPORTS) exposes Windows NT low-level definitions and symbols for user-mode programming, and also supplement a few CRT functions to allow program depends ntdll.dll only.

• Low-level definitions (i.e. NT*/Zw*, Rtl*, Ldr*, PEB, TEB, KUSER_SHARED_DATA, ...)
• Missing symbols in Lib (i.e. ntdll.dll!MD5Init, KERNEL32.dll!CreateProcessInternalW, SECHOST.dll!LsaLookupTranslateSids, ...)
• CRT functions or symbols (i.e. GS, RTC, malloc, free, ...)

Install and usage

General usage

1. Install Wintexports nuget package or add Wintexports headers (required) and libs (optional) to your project.

2. Include Wintexports header (Wintexports/Wintexports.h) instead of Windows.h in the source which you want to access low-level features.

   #include <Wintexports/Wintexports.h>

3. Then you can access all the low-level features supplemented by Wintexports.

   HANDLE CsrPid = CsrGetProcessId();

Advanced usage: Strip Microsoft C Runtime to make program depends Ntdll only

1. Set "Omit Default Library Name" (/Zl) in compiler setting, then MSVCRT will not be linked by default.

2. Link Wintexports CRT instead if /Zl switch is on.

   #if defined(_VC_NODEFAULTLIB)
   #pragma comment(lib, "WIE_CRT.lib")
   #endif

3. If Wintexports CRT (depends on Ntdll only) supplemented all missing symbols after stripping MSVCRT, the build will success and program will works well.

Advanced usage: Get more system Dll exports

Link following libs Wintexports supplemented:

• Ntdll_Hash.lib: Hash functions in ntdll, i.e. (A_SHA/MD5/MD4)(Init/Update/Final).
• WIE_WinAPI.lib: Windows SDK missing API, i.e. KERNEL32.dll!CreateProcessInternalW, SECHOST.dll!LsaLookupTranslateSids, ...

Requires Visual Studio 2019 and above with corresponding SDK, support x64/x86/ARM64 platform targets.

Project Wintexports in solution is a demo, accesses low-level system calls and functions, depends Ntdll only.

Caution

In alpha stage, do not use on production environment.
