# Shared

---

## Object Definition

```c
typedef struct _kpl_shared {
    KPL_SLAB_HEADER(_kpl_shared);
    void *data;
    kpl_atomic_queue queue;
    _Atomic uint32_t lock;
    bool mark;
} kpl_shared;
```

## Mutating

1. Before adding to the `queue` do `value = lock++`
2. Add to the queue
3. If `value` is `0` the thread does an async schedule of the mutator task, otherwise the thread moves on

### Mutator Task

1. Get task from `queue` and run task
2. After task completion, do `value = --lock`, stop if `value` is `0`, otherwise repeat
