创建日志文件周期性开源解决方案？ [英] Open-source solutions for creating a cyclical logfile?

问题描述

if (!wheel) { wheel = new Wheel(); }   // or some such

我的谷歌眼镜今天不工作太清楚了。我想这其中一定是codeD已经一个极大次，寻找一些开放源码软件code，但找不到任何。

My google goggles aren't working too well today. I figured this one must have been coded a gazillion times already and was looking for some FOSS code, but couldn't find any.

在我重新发明的球形轴周围的设备，任何人都可以点我在一个网址？

Before I reinvent the spherical axle-surrounding device, can anyone point me at a URL?

我用C编码嵌入式系统（爱特梅尔UC3），但是这不应该使任何区别，只是解释为什么我需要一个周期性的日志文件（因为有限的存储）。

I am coding in C for an embedded system (Atmel UC3), but that shouldn't make any difference, just explain why I need a cyclical logfile (because of limited storage).

我想将事件记录到文件中在SD卡上，当达到一定规模我要开始在开始重新动笔。所有网址是什么？ （固定条目大小是确定的;否则，它可能会在重叠讨厌）。

I want to log events to a file on an SD card and when the reaches a certain size I want to start writing again at the start. Any URLs for that? (fixed entry size is ok; otherwise it might get nasty on wraparound).

在此先感谢1,000,000！

Thanks a 1,000,000 in advance!

推荐答案

Sourceforge上有一个名为循环日志的项目，该项目可能会你所需要的。

Sourceforge has a project called Cyclic Logs which may be what you need.

如果不是，这不是最难实现的事情。只需把它像一个正常的循环内存空间。但不是有它驻留在内存中有它驻留在磁盘上。

If not, it's not the hardest thing to implement. Just treat it like a normal cyclic memory space. But instead of having it be resident in memory have it reside on the disk.

（维持的指针日志的头部和日志的末端（增量根据需要））

( maintain a pointer to the head of the log and the end of the log ( increment as needed ))

存储这些作为标题来记录或作为其他平面文件。

Store those as headers to the log or as another flat file.
