/**
|
||
|
|
* @file headers.c
|
||
|
|
* @brief Checks that a public header can be the first thing a caller includes.
|
||
|
|
*
|
||
|
|
* The assertion here is the compile, not anything main() does. `akgl/controller.h`
|
||
|
|
* declares its binding handlers as taking an `akgl_Actor *` and once did not
|
||
|
|
* declare that type, so every translation unit that reached for it before
|
||
|
|
* `akgl/actor.h` failed with "unknown type name 'akgl_Actor'". `src/controller.c`
|
||
|
|
* never noticed, because it includes `akgl/game.h` first.
|
||
|
|
*
|
||
|
|
* One header per file, deliberately. A second `#include` after the first proves
|
||
|
|
* nothing about the second: by then the first has already dragged its
|
||
|
|
* dependencies in. Covering another header means another file like this one.
