napi_unref_threadsafe_function

NAPI_EXTERN napi_status
napi_unref_threadsafe_function(napi_env env, napi_threadsafe_function func); 拷贝

• [in] env：调用 API 的环境。

  ¥[in] env: The environment that the API is invoked under.

• [in] func：要取消引用的线程安全函数。

  ¥[in] func: The thread-safe function to unreference.

该 API 用于指示在主线程上运行的事件循环可能会在 func 被销毁之前退出。与 uv_unref 类似，它也是幂等的。

¥This API is used to indicate that the event loop running on the main thread may exit before func is destroyed. Similar to uv_unref it is also idempotent.

此 API 只能从主线程调用。

¥This API may only be called from the main thread.
