Detailed Description

Cookbook Chapter 3: Creating a Stateful Callback.

This example demonstrates how to create a "closure" or stateful callback. This is essential when a C library's callback mechanism does not provide a void* user_data parameter, but your handler still needs access to application state.

infix_reverse_create_closure is used for this. It takes a generic handler function and a void* pointer to your state, which can be retrieved inside the handler.
