首先在自己的程序中#include<errno.h> 添加打印errno的语句 printf("errno is: %d\n",errno); 根据errno的值查错. errno的不同值的含义: 以下来自linux 2.4.20-18的内核代码中的/usr如何查看errno 错误代码 /include/asm/errno.h #ifndef _I386_ERRNO_H #define _I386_ERRNO_H #define EPERM 1 /* Operation n…

在编写应用层程序时,有时需要延时一下,这个时候该怎么办呢? 在内核代码中,我们经常会看到这样的头文件使用#include <linux/delay.h>,心想着直接调用这个就可以了吧!可是在编译时发现,压根通不过, 提示错误如下:error: No such file or directory. 是不是觉得很奇怪,明明文件是存在的,怎么就不能调用了,而且内核很多文件调用得很欢.这是为什么呢? 因为内核程序跟应用程序是有区别的,有些特殊的内核头文件编译器不允许被应用程序调用.故编译应用程序使用内…
