Im writing Python extension module with threads and hookers. I need to throw exception from one of my threads to main Python thread. For this Im using
int PyThreadState_SetAsyncExc(unsigned long id, PyObject *exc)
. In the documentation sayd:Nothing easier. But when I call
PyThreadState_SetAsyncExc
withException
(actuallyPyExc_Exception
) instance asexc
, I getI can read:), so I tried put not a class instance (as stated in docs, I believe), but class object directly as
exc
and it worsk. But, as a result, I cannot pass arguments to it.This code causes system error in main thread:
This code causes expected
Exception
in main thread:Full error text, IDLE shows:
So, I expected
PyThreadState_SetAsyncExc
supports exception instance-objects, but it looks like it supports only class/type-objects. Am I correct? Or maybe I do it wrong?
