Hello Nathaniel,

thanks for the pointer, that's what I need.

However, reading the documentation you linked, it looks like the new
buffer protocol is also available in Python 2.6, and I don't have the
need to support older versions, and this is confirmed by the python
documentation:

https://docs.python.org/2.7/c-api/buffer.html

So the issue is just on how to tell SWIG to implement this interface in
the wrappers it generates. Does anyone have a pointer to some relevant
documentation or examples?

Thanks!

Cheers,
Daniele
