| # Create a `wrapper.h` Header |
| |
| The `wrapper.h` file will include all the various headers containing |
| declarations of structs and functions we would like bindings for. In the |
| particular case of `bzip2`, this is pretty easy since the entire public API is |
| contained in a single header. For a project like [SpiderMonkey][spidermonkey], |
| 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 `wrapper.h` entry point for `bindgen`. |
| |
| Here is our `wrapper.h`: |
| |
| ```c |
| #include <bzlib.h> |
| ``` |
| |
| This is also where we would add any [replacement types](./replacing-types.md), |
| if we were using some. |
