Calling c function from python
 

Hi all,

I am a newbie to python and am not sure,what i am doing is correct or not ,i wanna call c function from within python.
i have my python program as:

import DLL



if __name__ == "__main__":

    for i in range(1,6):

         DLL.RECEIVE_FROM_IL_S(10,50)

here RECEIVE_FROM_IL_S() is c function which i wanna call.And my c
function would be,

#include <stdio.h>

#include <windows.h>

#include <stdio.h>

#ifdef _DEBUG

  #undef _DEBUG

  #include "python.h"

  #define _DEBUG

#else

  #include "python.h"

#endif



PyObject* _wrap_RECEIVE_FROM_IL_S(PyObject *self, PyObject *args)

{

    FILE* fp;

    PyObject* _resultobj;

    int i,j;



    if( !(PyArg_ParseTuple(args, "i",&i,&j)))

    {

      return NULL;

           

    }



/*Here if i want to call another c function say SEND_TO_IL(),what shud i be including*/



        fp= fopen('fileName.txt', "w");

        fprintf(fp, "i=%d   j=%d" , i,j);

             fclose(fp);



     _resultobj = Py_None;

    return _resultobj;  



}



static PyMethodDef MY_DLL_methods[] = {

      { "RECEIVE_FROM_IL_S", _wrap_RECEIVE_FROM_IL_S, METH_VARARGS },

      { "FUNC_CALL" , function,METH_VARARGS },

      { NULL , NULL}

      };



__declspec(dllexport) void __cdecl initDLL(void)

  {

    Py_InitModule("DLL",MY_DLL_methods);

  }

Also, if i don't want to pass any args to RECEIVE_FROM_IL_S from python what shud i do.

Regards,
john

Re: Calling c function from python
 

Are you following an example from a book?

Normally I would use the ctypes module from: http://starship.python.net/crew/theller/ctypes/
