Explain what you mean by "key up."

if(!key[KEY_BLAH])

GetKeyAsync()

To elaborate on the "if(!key[KEY_BLAH])" :

1char old_key[KEY_MAX];
2// on startup
3for (int i=0; i < KEY_MAX; i++)
4   old_key<i> = key<i>;
5 
6// Now call this 50 times a second or more, so you
7// don't miss an event:
8for (int i=0; i < KEY_MAX; i++)
9{
10   if (key<i> && ! old_key<i>)
11   {
12      // handle "key on" here
13      //
14   }
15   else if (! key<i> && old_key<i>)
16   {
17      // handle "key off" here
18      //
19   }
20   old_key<i>=key<i>;
21}
