# rt_darwin

Darwin (macOS) **real-time platform controls**: monotonic clock, thread QoS,
page locking.

```toml
[dependencies]
rt_darwin = "*"
stdlib = "*"
```

```cplus
import "rt_darwin/clock" as clock;
import "rt_darwin/thread" as thread;
import "rt_darwin/mem" as mem;
import "stdlib/result" as result;

let t0: u64 = clock::now_monotonic_ns();
let _r: result::Result[i32, i32] = thread::set_current_priority(thread::Priority::RealtimeAudio);
```

Portable structures (SPSC ring, pool) live in **`rt`**, not here.
