I am very new to the python C API, and have written a simple type
called SU2 that has 4 members that are all doubles. Everything seems
to work fine (can import my module and instantiate the new type and
act on it with various methods I have defined), except for when I
attempt to use my new type with multiprocessing.Queue (by the way I am
working with python 2.6).
So when I declare my object instance and call the put() method on the
Queue instance, the object I get out with the get() method of the same
Queue instance is not the same object. The four members of the
object are all coming through as all zeros. Below is the snippet of
code.
Are you on Windows? multiprocessing uses pickles to transfer objects
between processes. See if you can dump and load those kind of objects. If
not, you may need to implement __getstate__/__setstate__ or __reduce__
See http://docs.python.org/library/pickle.html
