Answer 1

use Jordan Sissel's excellent utility xdotool.

http://www.semicomplete.com/projects/xdotool/

it provide XWarpPointer wrapper function like xdo_mousemove(), here is some example:

Display *display = NULL;
xdo_t *xdo = NULL;

void mouse_left_down(int x, int y)
{
  xdo_mousemove(xdo, x, y, 0)
  xdo_mousedown(xdo, CURRENTWINDOW, Button1); 
}

void mouse_left_up(int x, int y)
{
  xdo_mouseup(xdo, CURRENTWINDOW, Button1, 1, 0); 
}

void mouse_left_double_click(int x, int y)
{
  xdo_mousemove(xdo, x, y, 0);
  xdo_click_multiple(xdo, CURRENTWINDOW, Button1, 1, 0);
  doubleclick = TRUE;
}

int main()
{

  display = XOpenDisplay(NULL);
  if(display == NULL)
  {
    fprintf(stderr, "can't open display!\n");
    return -1;
  }
  xdo = xdo_new((char*) display);

  //some task here
  // ...

  return 0;
}
