How to convert C++ header file to delphi -

i'm converting c++ header delphi pas file. first, converted c++ header using headconv 4.0 dr.bob module. failed compiling. can converting?

****** c++ header ******

#if !defined(____kkk_module__)  #define ____kkk_module__  #ifdef kkk_module_exports  #define kkk_module_api extern "c" __declspec(dllexport)  #else  #define kkk_module_api extern "c" __declspec(dllimport)  #endif  kkk_module_api int _stdcall kkk_creat();  ...... 

above code converted delphi code leads error below;

****** delphi code ******

{$ifdef kkk_module_exports}  const   kkk_module_api = extern 'c' __declspec(dllexport);  **//error**  {$else}  const   kkk_module_api = extern 'c' __declspec(dllimport);  **//error**  {$endif}  var   kkk_creat: function: kkk_module_api int cdecl  {$ifdef win32} stdcall  {$endif};  ......... 

cause of error 'extern' not reserved syntex of delphi. don't know how replace delphi code , need help.

that not c#, c++.

the conditional section common pattern allow header file used both when building library , when importing it. importing don't need translate part.

you left single function:

extern "c" __declspec(dllimport) int _stdcall kkk_creat(); 

the use of extern "c" suppresses c++ name mangling. don't translate that.

loosely, translate __declspec(dllimport) external directive.

translate to:

function kkk_creat: integer; stdcall; external libname; 

where libname string containing name of dll.

you need check name used export function. if library built without .def file function names decorated. function named kkk_creat@0. use tool dumpbin or dependency viewer check exported function names in dll.

fwiw, i've never found effective general purpose header translator , have found best manually, or write bespoke header specific translator.
