napi_ref_threadsafe_function

NAPI_EXTERN napi_status
napi_ref_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：要引用的线程安全函数。

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

此 API 用于指示在主线程上运行的事件循环在 func 被销毁之前不应退出。与 uv_ref 类似，它也是幂等的。

¥This API is used to indicate that the event loop running on the main thread should not exit until func has been destroyed. Similar to uv_ref it is also idempotent.

napi_unref_threadsafe_function 既没有将线程安全函数标记为可以被销毁，也没有 napi_ref_threadsafe_function 阻止它被销毁。napi_acquire_threadsafe_function 和 napi_release_threadsafe_function 可用于该目的。

¥Neither does napi_unref_threadsafe_function mark the thread-safe functions as able to be destroyed nor does napi_ref_threadsafe_function prevent it from being destroyed. napi_acquire_threadsafe_function and napi_release_threadsafe_function are available for that purpose.

此 API 只能从主线程调用。

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