   What is the difference between ctypes and pointer() in Python?

   • ctypes exports the byref() function which is used to pass parameters by reference. The same effect can be achieved with the pointer() function, although pointer() does a lot more work since it constructs a real pointer object, so it is faster to use byref() if you don’t need the pointer object in Python itself:

   How to create C callable function pointers from Python callables?

   • In ctypes, we can define the cell class and set the _fields_ attribute later, after the class statement: Let’s try it. We create two instances of cell, and let them point to each other, and finally follow the pointer chain a few times: ctypes allows creating C callable function pointers from Python callables.

   What is ctypes in Python?

   • ctypes is a foreign function library for Python. It provides C compatible data types, and allows calling functions in DLLs or shared libraries. It can be used to wrap these libraries in pure Python. Note: The code samples in this tutorial use doctest to make sure that they actually work.
