Where are the Windows API functions defined?

Question

when you need to use a function, you include the header file, but does the function code define it?

Answer 1

Dave, the code lives in different and many DLL files in the Windows \ system32 directory.

Answer 2

The actual code that implements the Win-32 API is defined in various DLLs on your system. These DLLs have names such as kernel32.dll, comctl32.dll, etc. You will find them in C: \ Windows \ System32.

What usually happens is that you bind your code to kernel32.lib, etc., which has a little code to dynamically load the DLL when your program starts. This allows Win32 API functions to access DLLS directly.
