Hi all,
I'm trying call Python from inside of a C thread that's running in a
Python extension I've written and I am not having much luck. My C
thread function consists of simply this, and I get a segmentation
fault from Python:
void start_routine(union sigval foo) {
PyGILState_STATE gstate;
gstate = PyGILState_Ensure();
// Calls to Python code will go here...
PyGILState_Release(gstate);
};
I added a printf() and can see that the fault happens *after* the call
to PyGILState_Release(). Apparently I'm monkeying up something
fundamental in Python, and this is really simple so I must be missing
something big.
The context is that I'm adding support for mq_notify() to my posix_ipc
extension. A process can register via mq_notify() to have a new thread
started when a message appears in a message queue. I've got this
working when my thread code is pure C, now I'm trying to add a call to
a user-specified Python function.
Thanks
Philip
