+
+Returns `napi_ok` if the API succeeded. If a non-detachable `ArrayBuffer` is
+passed in it returns `napi_detachable_arraybuffer_expected`.
+
+Generally, an `ArrayBuffer` is non-detachable if it has been detached before.
+The engine may impose additional conditions on whether an `ArrayBuffer` is
+detachable. For example, V8 requires that the `ArrayBuffer` be external,
+that is, created with [`napi_create_external_arraybuffer`][].
+
+This API represents the invocation of the `ArrayBuffer` detach operation as
+defined in [Section 24.1.1.3][] of the ECMAScript Language Specification.
