# Memory Pool

---

## Object Definitions

```c
#define POOL_HEADER(STRUCT) struct STRUCT *prev, *next; uint32_t obj_size

typedef struct _kpl_pool_obj {
    POOL_HEADER(_kpl_pool_obj);
} kpl_pool_obj;

typedef void kpl_pool_on_fn(void *obj);

typedef strut {
    _Atomic int32_t allocs;
    kpl_pool_obj *root;
    kpl_pool_on_fn *on_init, *on_free;
    pthread_mutex_t mutex;
} kpl_pool;

static kpl_pool_obj *kpl_pool_head;
```

## Object Size

The max size of an object in the pool is 2 \*\* 32

This allows for 4 aligned bytes after the `POOL_HEADER` macro
