Win32 and string functions

[TerribleTony]

I'm working through some assignments for class using Visual Studio 2008, and I noticed that I seem to be able to use c-string manipulation functions like strcmp(), strcat(), etc. without including the cstring header file. I'm also able to do Unicode functions like wcscat_s() without including any extra headers.

Is this simply a normal side-effect of #include <windows.h>? The text we're using is written around Visual Studio 2003 (it's an older text, obviously) and says that we should have to #include <cstring> to have access to these functions.

This is all basic Win32 API stuff, no MFC or anything yet. (It's introduced next chapter.) I'd like to understand what's going on here before I move on any further.

The project was created as a Win32 application; empty project. Only preprocessor statement is #include <windows.h>

Thanks!

The header files have been updated a number of times, so even though the code was VS 2003, the header files are VS 2008, since that's what you're using.
