鼠标接口中的链接器错误

Question

链接器会在initgraph和close graph

处出现溢出错误

#include<dos.h>
#define DETECT 0
union REGS in,out;
void detectmouse()//no declaration(prototype)?
{
    in.x.ax=0;
    int86(0x33,&in,&out);
    if(out.x.ax==0)
    {
        printf("Fail to initialize the mouse.");
    }
    else
    {
    printf("Mouse succesfully initialized.");
    }
    getch();
}

void showmousegraphics()//show mouse in graphics mode
{
    int driver=DETECT,mode;
    initgraph(&driver,&mode,"c:\\tc\\bgi");
    in.x.ax=1;
    int86(0X33,&in,&out);
    getch();
    closegraph();
}
void main()
{
    detectmouse();
    showmousegraphics();

}

啊，你可能在DOS上使用了一些旧的编译器。在这种情况下，您必须在编译时选择大内存模型，以便您可以拥有超过64kB的代码。
