Well, I believe I should problably use the PyArray_API instead (http://www.velocityreviews.com/forums/t358140-re-dynamically-loaded-librarie...), since it seems it's implemented in NumPy for this exact reason(?). Can anyone point me in the direction of a good step-step guide og using this api to export function pointers from NumPy to your own modules?

Hi

I haven't worked very much with NumPy and Python and hope some assistance :-)

I need access to a functionpointer in my own Python module. This functionpointer is available in a modified NumPy module. I would like to pass the functionpointer to my module when I import it in the Python runtime. Before importing my module I've already imported the NumPy module, and this is fine by me - I don't necessarily need my own module to handle the import of NumPy...

My question concerns how I should modify NumPy source code to be able to use the method of passing CObjects as described here: http://docs.python.org/release/2.5.2/ext/using-cobjects.html

Can anyone tell me where I should add the C-Object in NumPy? I tried to add it to the "multiarray" module (in the file multiarraymodule.c), but it dosen't look like this module is available for import (as in PyImport_ImportModule("multiarray"); in my own module - the return value of this is null). However, if I try PyImport_ImportModule("numpy"); it seems like I get a module imported, but this module does not have the CObject added. This is not surprising, since I added it to the "multiarray" module.

I believe I can solve my problem by adding the CObject to the "numpy" module instead, but in what file or files should I make modifications to do this?

Alternatively, how can I make the "multiarray" module available for import by my own module?
