Hello Gabriel, I just recently discovered that struct.pack does return a string. Everything works fine now. Thanks for the heads up!
static PyObject * sendMessage(PyObject *self, PyObject *args) { char *msg = ""; int len; if (!PyArg_ParseTuple(args, "s#", &msg, &len)) return NULL; ret = sctp_sendmsg(connSock, msg, len, 0, 0, 0x03000000, 0, 0x01, 0, 0); return Py_BuildValue("l", ret); } ---- Alvin Delagon
