Linux errno 错误比较表

副标题#e#

errno 在 <errno.h> 中界说,错误 Exx 的宏界说在 /usr/include/asm-generic 文件夹下面的 errno-base.h 和 errno.h,别离界说了 1-34 、35-132 的错误界说。

strerror() 函数依据 errno 值返回错误描写字符串,下面措施打印比较表:

01.#include <errno.h>

02.#include <string.h>

03.#include <stdio.h>

04.

05.int main()

06.{

07.    int i;

08.    for(i = 0; i < 140; ++i)

09.    {

10.        errno = i;

11.        printf("errno %d :\t\t%s\+n",i,strerror(errno));

12.    }

13.    return 0;

14.}
