1、万高建材:http:/ 经常会遇到此类问题 “当你进行了一些不当操作,系统会给你错误提示” ,这些错误提示在操作系统中都是错误编码的,每一个提示对应一个错误编码,错误编码供程序代码中方便调用,接下来我们会打印出linux 操作系统的错误编码及提示,如下:一、系统环境系统版本:内核版本:二、程序代码代码如下:三、编译运行结果如下:rootCentOS6 erro_num# gcc error_num.crootcentos6 erro_num# ./a.out0:Success1:Operation not permitted2:No such file or directory3:No suc
