This example demonstrates how you can wrap a C API that has a callback interface, so that you can pass Python functions to it as callbacks. The files cheesefinder.h and cheesefinder.c represent the C library to be wrapped. The file cheese.pyx is the Pyrex module which wraps it. The file run_cheese.py demonstrates how to call the wrapper.

The file run_cheese.py demonstrates how to
call the wrapper.
