## Members

### Common operations

- [`Cancelled`](/en/ocaml/latest/reference/libtmux_unix-cancellation-cancelled/) (exception)
- [`with_`](/en/ocaml/latest/reference/libtmux_unix-cancellation-with_/) (function): Own a cancellation token for the callback's lifetime. Leaving the scope cancels outstanding waiters and releases its descriptors after they finish. An escaped token is cancelled and cannot be reused.

### Other members

- [`cancel`](/en/ocaml/latest/reference/libtmux_unix-cancellation-cancel/) (function): Wake waiters. Safe from another domain or systhread, but not from a signal handler. Repeated calls and calls after scope exit have no effect.
- [`t`](/en/ocaml/latest/reference/libtmux_unix-cancellation-t/) (typealias)
