How to properly handle the keyboard with allegro?

edit: It has been fixed

What I do now gets by, but it clearly doesn't handle like a regular keyboard. It misses key presses every so often, and it's highly annoying. I downloaded an allegro game off allegro.cc last night, 3579 or something like that, and it had similar issues where it couldn't keep up with a fast typing user and would mis-read keys.

All I'm looking for is to be able to properly handle keyboard input as it regularly is in a windows environment. Can anyone offer some direction?

What are you doing now in your input code?

Well, I haven't gotten into the meat of it yet. It's just debug stuff. Here is the call to the function that checks the keys:

    if (keyboard_needs_poll())
    {
        poll_keyboard();
    }
       
    if (DEBUG == true)
    {
        Debug->CheckKeys();    
    }

and here's the CheckKeys function that is just kinda mangled together. It kinda works but notsomuch, hehe

1void objDebug::CheckKeys()
2{
  static bool F1_p = false;
  static bool F2_p = false;
              
  if (key[KEY_ESC])
  {
      GameManager->SetQuit(true);
  }
  
  if (key[KEY_F1] && !(F1_p)) 
  {
      if (key_shifts & KB_CTRL_FLAG)
      {
          if (mouse_info == true)
          {
              mouse_info = false;
          }
          else
          {
              mouse_info = true;
          }
          F1_p = true;
      }
  }
  else if (!key[KEY_F1])
  {
      F1_p = false;
  }    
  
  if (key[KEY_F2] && !(F2_p))  
  {
      if (key_shifts & KB_CTRL_FLAG)
      {
          if (timer_info == true)
          {
              timer_info = false;
          }
          else
          {
              timer_info = true;
          }
          F2_p = true;
      }
  }
  else
  {
      F2_p = false;
  }
50}

            {
                timer_info = true;
            }

timer_info = !timer_info;Both snippets do the same. You decide Same applies for the mouse_info variable.

hehe so they do :p thanks for the shortcut
