I have one question about Call Back modifires , for example
to write winMain() Function the syntax is :

int WINAPI winMain(){}

and I read in many books WINAPI = it is a callback modifires which calls function _stdcall...

I review many time C & C++ language I could not find any thing by this description " CALLBACK"..
I am familir with c/c++ functions and I know Macros that can be defined by using #define statment...

Kindly if any one can expalin this concpet in simple way to scratch this basic point for winAPI function..

Also I read in one book .. this is a syntax to call function by using Pascal Language ?? But as I know WinAPI is written by C language..

I hope I will get a good explanations for this point..

My Best Regards..
