int main() {
    Display *display = XOpenDisplay(NULL);
    Window window = XCreateSimpleWindow(display, DefaultRootWindow(display), 0, 0, 200, 100, 1, BlackPixel(display, DefaultScreen(display)), WhitePixel(display, DefaultScreen(display)));
    XMapWindow(display, window);

    XWindowAttributes attributes;
    XGetWindowAttributes(display, window, &attributes);

    XGetGeometry(display, window, &root_attributes.root, &attributes.x, &attributes.y, &attributes.width, &attributes.height, &attributes.border_width, &attributes.depth);

    printf("Window geometry: x=%d, y=%d, width=%d, height=%d, border_width=%d\n", attributes.x, attributes.y, attributes.width, attributes.height, attributes.border_width);

    XCloseDisplay(display);
