大哥门教我这段什么意思啊
hidegb()
{ union REGS regs;
regs.h.ah=1;
regs.h.ch=15;
regs.h.cl=0;
int86(0x10,®s,®s);
}

appeargb()
{ union REGS regs;
regs.h.ah=1;
regs.h.ch=15;
regs.h.cl=14;
int86(0x10,®s,®s);
}

这种什么regs.h.ah是什么东东
union REGS regs 什么意思
f[i].data[1]之类的是什么格式函数
诶~老师变态，C才学3个月编什么PC TOOLS
把高年级的拿来还看不懂，老师要写解释~~~
救我

[hcj2002]

union REGS {
struct WORDREGS x; //关于字（16位）寄存器的结果体
struct BYTEREGS h; //关于字节（8位）寄存器的结果体
};

int86: general 8086 software interrupt //通用8086的软件中断

int int86(int intno, union REGS *inregs,
union REGS *outregs);



This function loads the CPU registers with the
values stored in inregs, issues the interrupt
intno, and then stores the resulting CPU
register values in outregs.


程序的意思应该是设置文件的属性！
