如何在xwindow中移动鼠标指针？

Question

谁能告诉我怎样用鼠标移动xwindow库来移动鼠标指针？我读了一些帖子，要求我写入/dev中提供的鼠标设备文件。但出于某种目的，我只能使用xwindow库。

这段代码来自一个开源项目，用于将指针移动到屏幕上的(x，y)坐标。

#define SENSITIVITY 3        
static void movePointerTo(int x, int y){
        Bool result;
        int root_x, root_y, win_x, win_y; 
            unsigned int mask_return;
        root = DefaultRootWindow(dpy);
            Window window_returned;
        result = XQueryPointer(dpy, root, &window_returned, &window_returned, &root_x, &root_y, &win_x, &win_y,
                    &mask_return);
            if (result != True) {
                    fprintf(stderr, "No mouse found.\n");
                        return;
            }
            XWarpPointer(dpy, None,root, 0, 0, 0, 0, root_x+(x*SENSITIVITY),root_y+(y*SENSITIVITY));
        XFlush(dpy);
    }
