      Node.js N-API napi_unwrap

      Node.js N-API napi_unwrap

      新增于: v8.0.0 N-API version: 1 napi_status napi_unwrap(napi_env env, napi_value js_object, void** result); [in] env: The environment that the API is invoked under. [in] js_object: The object associated with the native instance. [out] result: Pointer to the wrapped native instance. Returns napi_ok if the API succeeded.

      Retrieves a native instance that was previously wrapped in a JavaScript object using napi_wrap().

      When JavaScript code invokes a method or property accessor on the class, the corresponding napi_callback is invoked. If the callback is for an instance method or accessor, then the this argument to the callback is the wrapper object; the wrapped C++ instance that is the target of the call can be obtained then by calling napi_unwrap() on the wrapper object.
