Hi,

I have written 'C' dll(MY_DLL.DLL) . I am importing 'C' dll in python file(example.py). I want to call python function from 'c' function. For your reference I have attached 'c' and python files to this mail. In my pc: python code is under the directory D:\test\example.py dll is under the directory C:\Program Files\Python\DLLs\MY_DLL.pyd

Here are the steps I am following.

step(1): I am calling 'C' function(RECEIVE_FROM_IL_S) from python. This 'C' function is existing imported dll(MY_DLL). step(2): I want to call python function(TestFunction) from 'C' function(RECEIVE_FROM_IL_S).

Python code is(example.py) :-

import MY_DLL

G_Logfile = None

def TestFunction(): G_Logfile = open('Pytestfile.txt', 'w') G_Logfile.write("%s \n"%'I am writing python created text file') G_Logfile.close G_Logfile = None #end def TestFunction

if __name__ == "__main__":

MY_DLL.RECEIVE_FROM_IL_S(10,50)

'C' code is (MY_DLL.c) :-

#include <windows.h> #include <stdio.h> #include <Python.h>

PyObject* _wrap_RECEIVE_FROM_IL_S(PyObject *self, PyObject *args) { FILE* fp; PyObject* _resultobj; int i,j;

if( !(PyArg_ParseTuple(args, "ii",&i,&j)))
{
   return NULL;
}
fp= fopen("RECEIVE_IL_S.txt", "w");
fprintf(fp, "i=%d   j=%d" , i,j);
fclose(fp);

/* Here I want to call python function(TestFunction). Please suggest me

some solution*/

_resultobj = Py_None;
return _resultobj;

}

static PyMethodDef MY_DLL_methods[] = { { "RECEIVE_FROM_IL_S", _wrap_RECEIVE_FROM_IL_S, METH_VARARGS }, { NULL , NULL} };

__declspec(dllexport) void __cdecl initMY_DLL(void) { Py_InitModule("MY_DLL",MY_DLL_methods); }

Please anybody help me solving the problem.

Cheers,

Praveen.
