Hey guys. I have an extension module written in C that abstracts and
simplifies a lot of what we do here. I'm observing some strange behavior
and wanted to know if anyone had any advice as to how I should start
tracking this down. More specific suggestions are obviously appreciated,
but I really do

So, here is my relevant code:
PyArg_ParseTuple(args, "O!", &PyType_vector3d, &arg1)
And here ismy error message:
argument 1 must be pylf.core.vector3d, not pylf.core.vector3d
I know PyType_vector3d "works" (as I can use them in the interpreter all
day long), and I know I'm passi
All of these are runtime errors. Using GCC4 and compiling perfectly with

Am I misunderstanding the point? :)

WELL, I figured it out--thanks to everyone's help. There were instances
of the object and I am a total moron.
Thanks again to everyone who helped me stomp this out. :)

Hey guys, sorry to ask another question of this nature, but I can't find
the answer or a single example of it anywhere. I'm sure it's been asked
before, but my google-fu isn't strong enough to find anything.
I have the following:
struct MyType {
PyObject_HEAD
First of all, let me say I really do appreciate--and frequently use--the
ample and easy to read Python documentation. However, there are a few
things I'm still unclear on, even after asking multiple questions here
on the list (thanks everyone!) and reading the "Extending" and
"Reference" docs from

It depends on how you want to manipulate the data in C. If you want
compile-time variable access to each float, yeah, 50 floats. :)
Probably what you want to do though is just keep the tuple as is and
iterate over it using the PySequence_* protocol:

On non-Windows system there are a ton of ways to do it--this is almost a
whole field unto itself. :) (D-BUS, fifos, sockets, shmfs, etc.) In
Windows, I wouldn't have a clue.
I guess this is a hard question to answer without a bit more
information. :)

I was looking through some code of my today and noticed this little gem
I wrote a few days back that I had totally forgot about:

...and then I went on to do:

Thought I'm not sure (and don't have time to test) I'd guess it's
because you haven't explicitly called the __init__ method chain.
i.e., B calls A, C calls B, etc.
This is probably where the actual data gets pulled into scope.

When using the C API and writing extension modules, how do you normally
pass a structure up into the python module? For instance, if I have a
structure:
typedef struct Foo {
Hmmm--I would also be interested in knowing the answer to this. I get
the exact same behavior as the OP (probably because it's the intended
behavior?)

I am mostly done with writing an extension module in C that wraps (and
makes easier) interfacing with libiw (the library that powers iwconfig,
iwlist, and friends on Linux). We're using this internally for a tool to
manage wireless connectivity. This is a million times better than
hundreds of invoc

When I add an object created locally to a mapping or sequence (that will
be returned from a function into an running instance of the Python
interpreter), I need to call Py_DECREF on the object, right?
Unfortunately, I really feel like the following code leaks memory...

If you want to get crazy you can poll() on one of the evdev nodes

we use to do the exact same thing you're talking about.
Each successful read from the device returns a 16-byte input_event

I honestly don't know the answer to this and I am entirely guessing
but--does it work without using the new module? That is:

foo = Foo()
foo.bar = _test.func2
