You can't pass any arbitrary C object to a Python function.
In this case you can use a PyCObject, a Python box around a void*
pointer.
Seehttp://docs.python.org/api/cObjects.html
Yup, I looked at http://www.python.org/doc/ext/using-cobjects.html
also. I could not find in this example where is CObject used or
converted back from Python to C.
Is there any tutorial which I can use for this?
If you have a C function that receives a PyCObject, just include the
relevant headers (cobject.h) and you can retrieve the original pointer
using PyCObject_AsVoidPtr:
void foo(PyObject *pyobj)
{
TOriginalType *porig;
porig = (TOriginalType *)PyCObject_AsVoidPtr(pyobj);
// do something with porig
}
