C++とWin32APIでマウスを押したりホイールをまわしたり

More than 3 years have passed since last update.
tmp.h
void    lclick(int x,int y){
    SetCursorPos(x,y);
    mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);
    mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);
}
void    rclick(int x,int y){
    SetCursorPos(x,y);
    mouse_event(MOUSEEVENTF_RIGHTDOWN,0,0,0,0);
    mouse_event(MOUSEEVENTF_RIGHTUP,0,0,0,0);
}
void    wheel(int w){
    mouse_event(MOUSEEVENTF_WHEEL,0,0,w,0);
}

あとは適当にlclick(120,300);等等と書けばカーソルが瞬間移動してスクリーン座標120,300を左クリックしてくれます。
wheel(-100);と書けばウィンドウが下にスクロールします。
他の人はSendInput関数を使う方法を紹介していますが私の環境ではなぜかスクリーンセーバが起動します。意味不明なので上記が堅実です。
