napi_async_cleanup_hook

与 napi_add_async_cleanup_hook 一起使用的函数指针。它将在环境被拆除时被调用。

【Function pointer used with napi_add_async_cleanup_hook. It will be called when the environment is being torn down.】

回调函数必须满足以下签名：

【Callback functions must satisfy the following signature:】

typedef void (*napi_async_cleanup_hook)(napi_async_cleanup_hook_handle handle,
                                        void* data); 拷贝

• [in] handle：在异步清理完成后必须传递给 napi_remove_async_cleanup_hook 的句柄。
• [in] data：传递给 napi_add_async_cleanup_hook 的数据。

函数主体应在最后启动异步清理操作，清理完成后必须在调用 napi_remove_async_cleanup_hook 时传入 handle。

【The body of the function should initiate the asynchronous cleanup actions at the end of which handle must be passed in a call to napi_remove_async_cleanup_hook.】
