1、使用了一个小程序输出所有的errno对应的error字符串，代码如下

#include <errno.h>

void showError(int err)

{

　　printf("errno : %5d , error : %s\n", err, strerror(err));

}

void showAllErr() 

{

　　int i = 0; 

　　for(;i < 256; i++)

　　{

　　　　showError(i);

　　}

}

int main(int argc, char * argv[])

{

　　showAllErr();

　　return 0;

}

 

2、运行上面代码，结果如下
