napi_adjust_external_memory | Node.js API 文档

新增于: v8.5.0 N-API 版本: 1

NAPI_EXTERN napi_status napi_adjust_external_memory(node_api_nogc_env env,
                                                    int64_t change_in_bytes,
                                                    int64_t* result);

[in] env：API 被调用时所处的环境。
[in] change_in_bytes：由 JavaScript 对象保持活动状态的外部分配内存的变化。
[out] result：调整后的值

如果 API 成功，则返回 napi_ok。

🌐 Returns napi_ok if the API succeeded.

此函数向 V8 指示由 JavaScript 对象保持活动的外部分配内存的数量（即指向本地插件分配的自身内存的 JavaScript 对象）。注册外部分配的内存会比平时更频繁地触发全局垃圾回收。

🌐 This function gives V8 an indication of the amount of externally allocated memory that is kept alive by JavaScript objects (i.e. a JavaScript object that points to its own memory allocated by a native addon). Registering externally allocated memory will trigger global garbage collections more often than it would otherwise.
