内嵌汇编疑问
代码目的：定位光标。
程序代码：int main()
{
__asm__ __volatile__("movl $0x00, %eax\n\t");
__asm__ __volatile__("movl $0x00, %ebx\n\t");
__asm__ __volatile__("movl $0x00, %edx\n\t");
__asm__ __volatile__("movb $0x02, %ah\n\t");
__asm__ __volatile__("movb $0x00, %bh\n\t");
__asm__ __volatile__("movb $0x20, %dl\n\t");
__asm__ __volatile__("movb $0x10, %dh\n\t");
__asm__ __volatile__("int $0x10\n\t");
printf("!\n");
return 0;
}运行时接受到SIGN就退出了。定位在__asm__ __volatile__("int $0x10\n\t");
