How to make a single keypress?

Question

Game development

In general, you need to prohibit a long press on a key, i.e. make one-time
here is part of the code

bool keyboard::IsMouseButtonUp(byte key, bool bonus, Logic *Logic_,SDL_Event event_)
{
    SDL_PollEvent(&event_);
    if(event_.type == SDL_MOUSEBUTTONUP && !bonus)
  {
    GetButtonDownCoords(event_);
    if (point.y >407 && point.y<444)
    {
      if (point.x >123 && point.x<190)
        setF(false, 0);
      if (point.x >228 && point.x<296)
        setF(false, 1);
      if (point.x >330 && point.x<401)
        setF(false, 2);
      if (point.x >436 && point.x<506)
      {
        if (getF(3))
          SetBet_(GetBet_() + 1);
        setF(false, 3);
      }
      if (point.x >543 && point.x<608)
      {
        setF(false, 4);

It is necessary because when you press it for a long time, startrotate () restarts where if (buttons [2]) is setF (true, 2) - press the F2 key and setF (false, 2) - release the F2 key, and here is the code for mouse button
