using namespace std;

void mousemove( HWND hwnd1, POINT p);
void left_mouseclick( POINT p );
int main()
{
      POINT p;
      p.x = 200;
      p.y = 200;

      HWND hwnd1;  // placeholder
      
      mousemove ( hwnd1, &p );
      left_mouseclick ( p );

      
      
      return 0;
}


void mousemove( HWND hwnd1, POINT p)
{
      ClientToScreen(hwnd1, p);
      SetCursorPos(p.x, p.y);
}

void left_mouseclick( POINT p )
{
      mouse_event(MOUSEEVENTF_LEFTDOWN,   p.x, p.y, 0, 0); // Left Key Down
      mouse_event(MOUSEEVENTF_LEFTDOWN,   p.x, p.y, 0, 0); // Left Key Down

}





I don't why, I know that my use of hwnd is problematic, but i don't know how other things are wrong.

Well, you have to initialize the HWND to hold a valid handle. Otherwise, that looks OK, except that you should give a short delay between the two clickes, e.g.

void left_mouseclick( POINT p )
{
      mouse_event(MOUSEEVENTF_LEFTDOWN,   p.x, p.y, 0, 0); // Left Key Down
      Sleep(400);
      mouse_event(MOUSEEVENTF_LEFTDOWN,   p.x, p.y, 0, 0); // Left Key Down

}
