report progress from C function

[Michael S]

Good day all.

I rewrote part of my program in C, it's a usually a
long task. I wanted to be able to report the progress
back to my python program. In my module (in addition
to the function that performs the above-mentioned
task) there is a function that returns the variable,
indicating the progress. However I am not sure how to
call it. Once I call the C function that does the work
(it's a while loop that takes minutes sometimes) I
can't call that progress function.
Any ideas?

Thanks in advance,
Michael

What do you expect your "python program" to be doing between calls to
the get_progress function?

Here's a sketch of one possible way of doing something useful: add the
following 2 args to your C "does the work function":
(1) Python function object to be called every n times around the while
loop or every nth other event or every n milliseconds or whatever
(2) n

BTW, why did you rewrite in C rarher than using Pyrex?

Cheers,
John

I downloaded Pyrex and ran it through their own
example. The code looks quite messy, and I even saw a
few "goto"s.

looked at the assembler output from your C compiler lately?

LOL! - is it even possible to code an if else without conditional jumps?
