Thank you for that suggestion. It allowed me to replace six lines of code with
one. :)

Hi and thanks very much for your comments on reference counting. Since I'm new
to the C_API that will help a lot. I know that reference counting is one of
the difficult issues with the C API.
I just posted a reply to Inada Naoki showing how I solved the problem I posted
yesterday.
Thanks

Right you are. In that case should I use Py_BuildValue and convert to tuple
(because it won't return a tuple for a one-arg), or should I just convert
pListStr to tuple? Thanks for your help.

Thanks for your reply.
I eliminated the DECREF and now it doesn't segfault but it returns 0x0. Same
when I substitute pListStrE for pListStr. pListStr contains the string
representation of the fileid, so it seemed like the one to use. According to

This is a follow-on to a question I asked yesterday, which was answered by

Ah, ok, that was the important piece of information that you omitted from
your previous posts. So

Ok, so you're looking for the C-level trace function in CPython, I guess.

In one case I have to check the return value of PyObject_Call, and if
its not of the correct return value,
I throw an exception, but I just get a simple output:

I think Steve was expecting that you wanted to debug into your program,
step into the call, and find the line yourself.
