How to make an API in C?
It helps if you understand what an API is. http://en.wikipedia.org/wiki/API





An API is not a function. It is the interface that a source code can use to work with a library. If your c files form a coherent library, compile them as a library file and give out the headers to appropriate functions. Obviously, design your library appropriately, so that you can expose a meaningful interface.
Reply:Yes, csanon has it right.





I'd just add/emphasize that your API is usually just


the function prototypes that you specify in a header (.h)


file (and any user defined types, structs, enums, etc,


that are required for use in calling the functions).
