  VOID FAR PASCAL wsleep(int iNrSeconds)
  {
      DWORD lCountStop = GetTickCount() + 1000L * (DWORD) iNrSeconds;

      while (GetTickCount() < lCountStop);
  }

  Of course there is one but with this approach: all CPU power is spend
  in that loop. 

while (GetTickCount() < lCountStop) Yield();
lets other Windows processes run while you're sleeping.  Even better is
to integrate the sleepiness with your program's message loop; see the
documentation on PeekMessage.
