log-cleaner's Introduction

log-cleaner

日志清理工具
作者:土司 skyer

优点:

1、保存了修改前的相关时间属性,以免被人发觉文件修改
2、算法参考:https://www.linuxquestions.org/questions/programming-9/fastest-memmem-4175481626/

缺点:

1、建议64位s系统下进行使用,MapViewOfFile在32位只能映射4G内存空间
2、只处理*.txt,*.log文件

学习:

1、这里对文件的内存操作是通过映射内存实现的,然后再用算法来进行遍历该内存,文件递归,内容通过偏移循环遍历修改,这也是一种好方法!
