高分求助！我想用C或者C++写一个获取当前鼠标位置的函数，就是getMousePosition的形式，返回两个整数x/y，怎么搞？？

[qinliu0425]

如题，另外。我想把这个功能放到一个dll中
请各位大虾帮忙。不慎感激

这得调用windows api了

#pragma comment(lib,"user32.lib")

void main()
{
LPPOINT lp;
lp =new POINT;
GetCursorPos(lp);
printf("%l\t%l\n",lp->x,lp->y);
delete lp;

}

VC 新建一个DLL工程
将上述代码改成你需要的形式,添加进去
设置接口
编译!

呵呵~lz就参考~GetCursorPos的做法传引用或指针参数进去就行了~

不然也可以将结果保存到一个DOWRD形态的变量中，高位WORD存x，低位WORD存y；
相关的宏：MAKELONG(low, high), LOWORD(x), HIWORD(x)~呵呵

调用GetCursorPos在windows上可以，但在linux上就不行了

[JoyerHuang_悦]

楼上的，是你自己说要做成dll的吧？？LINUX下面又不能用dll，所以没必要考虑这个API的移植呀。。
除非你又说，打算做成so格式的。
