A89: What's Wrong?



I have this function to wait for a key, but after I press one of the keys in the row it reads, keep returning the value of key2 instead of reinitializing it and waiting for another key press.  What did I do wrong?
 
int keywait()
{
 int key2=0;
 key2=0xFF;
 while(!(key2&0xFF))
  key2=_rowread(0xfffe);
 return key2;
}

If one is travelling faster than light, would he really travel back in time, or just be able to view past events again without being able to change them?
