I use something like this:
if (PyErr_Occurred()) {
if (PyErr_ExceptionMatches(ExceptionName)) {
/* do something about ExceptionName */
} else if (PyErr_ExceptionMatches(AnotherExceptionName)) {
/* if we want to get the exception string */
PyObject *errtype, *errvalue, *traceback;
PyErr_Fetch(&errtype, &errvalue, &traceback);
if(errvalue != NULL) {
PyObject *s = PyObject_Str(errvalue);
/* Now 'PyString_AS_STRING(s)'
contains C string of error message
do something with it
*/
Py_DECREF(s);
}
Py_XDECREF(errvalue);
Py_XDECREF(errtype);
Py_XDECREF(traceback);
}
}
Goof luck.
