I am developing C++ COM native code (unmanaged C++) using Visual Studio
2005. I do not take any new features of 64-bit platform, and currently my
code runs fine on 32-bit platform (e.g. Windows XP SP2).

I think in built-in C/C++ functions, there is no direct function call to
trim heading and trailing space characters, right? So, we have to implement
it manually by iterating the string to check character one by one.
