I am interested in passing binary data between python, numpy, and cython using the buffer protocol. Looking at PEP 3118, there appear to be some additions to the struct string-syntax that add suppo...

I'm working in with a C library that repeatedly calls a user supplied function pointer to get more data. I'd like to write a Cython wrapper in such a way that the Python implementation of that call...

I am in the process of extending the classes in our library (which supports Python 2.7) to support PEP 3118, which has been back-ported to 2.7. From the documentation, I need to initialize the tp...
