Windows光盘刻录API [英] Windows CD Burning API

问题描述

我们需要编程文件刻录到CD中，我们使用的是涡轮Borlands C ++开发一个C \\ C ++的Windows XP / Vista中的应用。

We need to programatically burn files to CD in a C\C++ Windows XP/Vista application we are developing using Borlands Turbo C++.

什么是最简单，最好的方法是什么？我们将preFER本机Windows API（这并不依赖于MFC），从而不依赖于任何第三方软件/驱动程序（如果可用）。

What is the simplest and best way to do this? We would prefer a native windows API (that doesnt rely on MFC) so as not to rely on any third party software/drivers if one is available.

推荐答案

我们使用以下内容：

存储文件，然后使用写烧伤。 GetCDRecordableInfo是用来检查当CD已经准备就绪。

Store files in the directory returned by GetBurnPath, then write using Burn. GetCDRecordableInfo is used to check when the CD is ready.
