| <p>The <code>wrapper.h</code> file will include all the various headers containing |
| declarations of structs and functions we would like bindings for. In the |
| particular case of <code>bzip2</code>, this is pretty easy since the entire public API is |
| contained in a single header. For a project like <a href="https://developer.mozilla.org/en-US/docs/Mozilla/Projects/SpiderMonkey/How_to_embed_the_JavaScript_engine">SpiderMonkey</a>, |
| where the public API is split across multiple header files and grouped by |
| functionality, we'd want to include all those headers we want to bind to in this |
| single <code>wrapper.h</code> entry point for <code>bindgen</code>.</p> |
| <p>Here is our <code>wrapper.h</code>:</p> |
| <pre><code class="language-c">#include <bzlib.h> |
| </code></pre> |
| <p>This is also where we would add any <a href="./replacing-types.html">replacement types</a>, |
| if we were using some.</p> |
