| 摘 要： | Windows下的硬件中断首先从Vhard-wareInt类中派生出一个类,定义构造函数并重载各个信号处理程序.调用类VhardwareInt的构造函数,指定IRQ.再在VxD初始化时,用new动态创建其派生类对象实例,对重载的中断通知处理程序编程.最后调用钩挂函数(hook)中断处理程序.成功钩挂后,还可调用Physical Unmark成员函数,确保允许中断处理.

| Abstract: | At first, a species was derived from Vhard-wareInt for the hardware interrupt process in Windows, structure function was defined and each signal processing program was reloaded. The structure function of VhardwareInt-like was called to designate IRQ. Then, the object example of derived species was created by using new dynamic condition. The interrupt process program of reloading interrupt notice was compiled, at last, the hook function was called to interrupt program. After hooking, the Physical Unmark member function was called to make sure the interrupt process. |
