You'll need to include the DLL header file, and link to the DLL lib file.

You can load a DLL explicitly too using LoadLibrary if you want.

is loadlibrary is c function or c++?

It is a Windows API function which can be used in both C and C++.

>> but why all code including windows.h

Because it's using Windows specific stuff. Remember, a DLL is a Windows construct, it's not part of C.

windows.h defines several things that you need, like LoadLibrary, GetProcAddress, etc. If your code is not using anything from windows.h, then you don't need to include it :)

Yes, it does, right here :

        http://msdn.microsoft.com/en-us/library/ms686944(VS.85).aspx

Note the first two lines of the code :

        // A simple program that uses LoadLibrary and
        // GetProcAddress to access myPuts from Myputs.dll.


May I ask why you gave a B grade ? That usually means that something was missing in the answer and/or that something is still unclear. If that's the case, you don't have to close the question yet, and can ask for clarification wherever needed. Us experts prefer getting the opportunity to earn an A grade ;)

Btw, as I said earlier, there is a simpler alternative, namely simply including the DLL header file, and linking to the DLL lib file. That's it ... nothing more - no LoadLibrary is needed in that case.
