Hi
If PyImport_ExecCodeModule have a two parameteres and second parameter is
PyObject type why you are make a call with a unsigned char value ?
If you search this function name into Google you will can found some
examples, use for example PyMarshal_ReadObjectFromString or
PyMarshal_ReadObjectFromFile
Bye
