在aysnc work 执行前,需要先 napi_acquire_threadsafe_function 获取线程安全函数,以确保线程之间的同步和互斥,再执行 work,完事后 release 线程安全函数 注意:napi_acquire_threadsafe_function 一般用于多线程之间的切换,如果 native 是单线程操作,无需其他线程,可以不使用 napi_
napi_threadsafe_function(简称tsfn)在使用时,常调用napi_acquire_threadsafe_function更改引用计数,确保tsfn不会意外被释放。使用完成后,应及时使用napi_tsfn_release模式调用napi_release_threadsafe_function方法,使引用计数回归到调用napi_acquire_threadsafe_function之前的水平,当引用计数为0时,tsfn才能正确释放。当env...

主线程创建了一个`napi_create_threadsafe_function`实例,并将其与回调函数`CallJs`关联起来。然后,创建了一个其他线程,该线程在循环中累加`sum`成员变量的值,并在每次循环中调用`napi_acquire_threadsafe_function`来获取对线程安全函数的访问权。 在主线程中,通过`napi_call_threadsafe_function`调用线程安全函数,...
napi_status status = napi_call_threadsafe_function(tsfn, data, napi_tsfn_nonblocking); 在这个例子中,我们使用线程安全函数[napi_call_threadsafe_function]来调用线程安全函数,并在Node.js的事件循环中异步执行。我们还可以选择使用[napi_acquire_threadsafe_function]和[napi_release_threadsafe_function]来管理线...
