Is there any other way I can implement the above?

But do you know of anything in Visual Studio 2008 or any other widely used library that can do the above?

#include <windows.h>

unfortunately Visual C++ 2008 has some issues with Boost::threads package

3) What is difference between static and dynamic linkage.

1) what do you actually mean? Would you be able to make the meaning clearer?

2) Why is Boost statically linking with my library? or is vice versa? what does that actually mean?
