libkcrt
libkcrt provides an easy way to use C Run-time Library from Windows Kernel exported from ntdll.dll in your user-mode applications.
I suggest you use VC-LTL for non-special cases, not the libkcrt.
Under Construction
Todo list
- Add basic memory allocation support for C and C++.
- Without defining the entry point manually.
- Add static variable initialization support.
Known Issues
- Run-Time Error Checks (/RTC) is not supported.
- C++ Exception Handling is not supported.
