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.
