C/C++底层实现指定磁盘只读
C/C++底层实现指定磁盘只读 收藏
燕狂徒写的驱动挂钩，限制磁盘只读， 用于保证涉密计算机的稳定，相当于将磁盘变成ROM #include "ntddk.h"
#include
#include #define DRIVERNAME "OnlyRead(GongXiPeng!)" // for use in messages typedef struct tagDEVICE_EXTENSION {

JAVA可以说是从C++发展起来的完全面向对象的开发语言,两者的实质区别是利益分属不同的公司:SUN和微软.对此微软发布了.NET与之抗衡.
从最新的Visual Studio .NET 2005看,.NET主要是4种语言:VB.NET, C#, C++.NET, J#.
VB.NET可以说是VB6的升级,但我认为VB.NET和C#已经是完全全新的语言了,两者的目的都是要打败JAVA这个竞� ......
1：类似junit的断言，只是在assert中的断言，如果不满足的话就程序退出。
比如
#include <assert.h>
int main(void)
{
assert(6 < 5);
system("pause");
return 0;
}
在执行到assert(6 < 5);
的时候因为不满足断言，于是程序退出。
如果不想让assert(6 < 5)起作用，就在最上面添加宏定义# ......

C的一大特色（却不被初学者所知）就是__attribute__机制。__attribute__可以设置函数属性（Function

__attribute__书写特征是：__attribute__前后都有两个下划 ......
