我正在尝试使用 NAPI 创建节点模块。我必须创建返回承诺的异步函数。我不希望 testasynfunction 会阻塞 NodeJS 事件循环。do_something_asynchronous 是一个同步函数。

napi_deferred do_something_synchronous(napi_env env,napi_deferred deferred){
  printf("\n3) Function called");
  //napi_deferred deferred;
  napi_value undefined;
  napi_status status;

  // Create a value with which to conclude the deferred.
  status = napi_get_undefined(env, &undefined);
  if (status != napi_ok) return NULL;
  sleep(5);
  // Resolve or reject the promise associated with the deferred depending on
  // whether the asynchronous action succeeded.
  if (false) {
    printf("\n5) Success\nXXXXXXX");
    status = napi_resolve_deferred(env, deferred, undefined);
  } else {
    printf("\nReject");
    status = napi_reject_deferred(env, deferred, undefined);
  } …
