Question

I need to convert this Line from C to Delphi.

Int CALLBACK EXPORT EXAMPLEFUNCTION(VOID){
  SETEVENT(hasync);
  Return Success;
}

Please i need some help.

thanks 😉

Answer 1

Kind of guessing here, because the style’s really messy, but I think that would translate something like this:

const Success = 1; //or whatever; might not be 1.
                   //assume a const definition for a value 
                   //called Success exists somewhere in scope

function EXAMPLEFUNCTION(): integer; stdcall; //CALLBACK = stdcall calling convention
begin
   SETEVENT(hasync); //hopefully this makes sense in context
   result := Success;
end;

That’s the best I can do without further context. The EXPORT declaration is a preprocessor macro, and it (probably) means that this is part of a DLL and that this is a function that’s supposed to be callable by programs that load the DLL. In Delphi, that’s not part of the function definition; instead, you put it in an exports clause.
