C ++ Linux GCC应用程序中的GUID [英] GUIDs in a C++ Linux GCC app

问题描述

我有很多运行这个Linux应用程序的服务器。我希望他们能够生成一个碰撞概率较低的GUID。我确信我可以从/ dev / urandom中提取128个字节，这可能会很好，但是有一个简单的&简单的方法来生成一个更相当于Win32的GUID？特别是，考虑到空间（以及MAC地址），时间和随机性？我不想为此取消对话框，我只想要 CreateGuid （）

I've got a bunch of servers running this Linux app. I'd like for them to be able to generate a GUID with a low probability of collision. I'm sure I could just pull 128 bytes out of /dev/urandom and that would probably be fine, but is there a simple & easy way to generate a GUID that is more equivalent to the Win32 one? Specifically, one that takes into account space (well, MAC address), time, and randomness? I don't want to call off the box for it, I just want something like CreateGuid()

推荐答案

互联网草案详细描述了一种类型的UUID，当我需要一个UUID实现并且不能链接到一个现有的图书馆的建筑原因。

This Internet Draft describes one type of UUID in great details and I have used a similar approach with great success when I needed a UUID implementation and could not link to an existing library for architectural reasons.

这文章提供了一个很好的概述。
