CAPI and thread safety

[Lane Brooks]

I am writing an extension module that needs to release the global
interpreter lock during some blocking I/O calls, but I need a mutex in
the C code to make some of the shared data in the extension module are
kept thread safe. Can anyone recommend a portable way to do this? I
could use a pthread mutex, but I do not think that is portable.

Are any of the python mutexes or locks exposed through the C API? I
could not find anything.

Thanks,
Lane

Look at Include/pythread.h. You can use PyThread_alloca te_lock to get
the threading abstractions that Python uses.

Thanks for the pointer. I'll check it out. That is what I was looking
for.
