because, lets face it, MSDN's search function sucks...
so to you gifted few, you MSDN ambassadors, the guys who can recall any and every Window's API function on a moment's notice... how do you do it??
The search function mostly yields 99% off-topic garbage (especially if you are looking for C code and not C++/C# code) and manually browsing the drop-down sections is like shopping for specialty items at a department store: the stuff you're looking for is always in the LEAST likely place you'd expect it be.
So what kind of cunningness must one employ to be able to find what they're looking for in MSDN?
