Dart是否支持与本机库的接口？ [英] Does Dart support interfacing with the native libraries?

问题描述

由于服务器端部分变得更加复杂，开发人员将需要利用现有的软件。因此，Dart是否支持与本机库（特别是C库）的接口？

As the server-side part becomes more complex, developers will need to leverage the existing software. So, does Dart support interfacing with the native libraries (C libraries, in particular)?

推荐答案

这是官方指南。

在独立的Dart VM（命令行应用程序）上运行的Dart程序可以通过本机扩展调用共享库中的C或C ++函数。本文介绍如何在Windows，Mac OS X和Linux上编写和构建此类本机扩展。

Dart programs running on the standalone Dart VM (command-line apps) can call C or C++ functions in a shared library, by means of native extensions. This article shows how to write and build such native extensions on Windows, Mac OS X, and Linux.

您可以提供两种类型的本机扩展：异步或同步。异步扩展在单独的线程上运行本机函数，由Dart VM调度。同步扩展直接使用Dart虚拟机库的C API（Dart Embedding API），并在与Dart隔离器相同的线程上运行。通过向Dart端口发送消息，并在应答端口上接收响应来调用异步函数。

You can provide two types of native extensions: asynchronous or synchronous. An asynchronous extension runs a native function on a separate thread, scheduled by the Dart VM. A synchronous extension uses the Dart virtual machine library’s C API (the Dart Embedding API) directly and runs on the same thread as the Dart isolate. An asynchronous function is called by sending a message to a Dart port, receiving the response on a reply port.
