Introduction

Our Perl examples throughout the book have plugged into the Perl API via an object-oriented interface that blurs the distinction between data structures and function calls. For better or for worse, there is no such blurring in the C API. Data is maintained in data structures. To work with these structures, you either access their fields directly or pass them to function calls to do the work for you. In this section, we work our way through the four central data structures in the Apache C API: the module, the request_rec, the conn_rec, and the server_rec.
