Hi Barry,

void handleError(const char* msg)
{ ....
PyErr_Fetch(&pyExcType, &pyExcValue, &pyExcTraceback);
PyErr_NormalizeException(&pyExcType, &pyExcValue, &pyExcTraceback);

PyObject* str_value = PyObject_Repr(pyExcValue);
PyObject* pyExcValueStr = PyUnicode_AsEncodedString(str_value, "utf-8",
"Error ~");
const char **strErrValue* = PyBytes_AS_STRING(pyExcValueStr);

//where *strErrValue* = "ImportError('Error: Reinit is forbidden')"
....
}

What we imported is a Python file which import some pyd libraries.

Thanks
Jason
