uLib
User mode C/C++ extended API library for Win32 programmers.
...It is licensed under the NNOSL open source license, a descendant of BSD
which adds a degree of developer protection from shameless profiteering.
I hope uLib will make Your life as a Windows programmer easier.
The full documentation is browsable on the project web page (link below),
and downloadable as .chm from the Files area.
Good luck on the path.
