根据错误码打印错误信息

errno 在 <errno.h> 中定义,错误 Exx 的宏定义在 /usr/include/asm-generic 文件夹下面的  errno-base.h 和 errno.h,分别定义了 1-34 、35-132 的错误定义。

strerror() 函数依据 errno 值返回错误描述字符串,下面程序打印对照表:

#include <errno.h>
#include <string.h>
#include <stdio.h>
 
int main()
{
    int i;
    for(i = 0; i < 140; ++i)
    {
        errno = i;
        printf("errno %d :\t\t%s\n",i,strerror(errno));
    }
    return 0;
}
