`async-signal` provides functions for handling process signals asynchronously in [Deno][].

Deno limitation: On Windows only `"SIGINT"` (Ctrl+C) and `"SIGBREAK"` (Ctrl+Break) are supported.

[Deno]: https://deno.com/

```typescript

import { asyncSignal, SignalError } from "@milly/async-signal";

import { delay } from "@std/async";

try {

  // When the block exits, the signal trap is removed.

  using intTrap = asyncSignal("SIGINT");

  // It resolves after 5 seconds or rejecets if Ctrl+C is pressed.

  await Promise.race([intTrap, delay(5000)]);

} catch (err) {

  // `intTrap` rejecets with `SignalError`.

  if (err instanceof SignalError) {

    console.error(`${err.signal} is trapped`);

  }

}

```
