什么是中断号?什么是AX寄存器? [英] What is an interrupt number?What is AX register?

问题描述

我想知道调用鼠标指针的程序中的中断号和AX寄存器是什么意思

Hi, I want to know what is meant by an interrupt number and AX register in a program that invokes mouse pointer

推荐答案

硬件使用中断号在发生某些外部事件时向操作系统发出信号. AX寄存器仅仅是CPU使用的通用寄存器.它们都不是特定于鼠标程序的(无论可能是什么).
看看此处 [

Interrupt numbers are used by the hardware to signal the operating system when some external event occurs. The AX register is merely a general purpose register used by the CPU. Neither of them are specific to a mouse program (whatever that may be).
Take a look here[^] for some information on how processors work.
