/**
|
||
|
|
* @file header_pool_override.c
|
||
|
|
* @brief Checks that the compile-time pool-size overrides in heap.h actually fire.
|
||
|
|
*
|
||
|
|
* `heap.h` wraps every `AKGL_MAX_HEAP_*` ceiling in an `#ifndef` so a game that
|
||
|
|
* needs more actors can define its own before including it. That mechanism was
|
||
|
|
* dead until 0.5.0: `actor.h`, `sprite.h` and `character.h` defined the same
|
||
|
|
* four unconditionally, and `heap.h` includes all three *above* its own
|
||
|
|
* `#ifndef` block, so whichever landed first won and the guard never fired. The
|
||
|
|
* override was documented, and did nothing.
|
||
|
|
*
|
||
|
|
* The assertion is the compile. Nothing here links against the pools -- it
|
||
|
|
* cannot, because the library was built with the default ceilings and this
|
||
|
|
* translation unit deliberately disagrees with it. That disagreement is the
|
||
|
|
* documented consequence of overriding a ceiling, not something this file is
|
||
|
|
* working around: the arrays are sized at compile time, so the library and
|
||
|
|
* everything linking it have to agree.
