pthreads, which only works in DOS and WinDOS due to severe bugs in NT,
or:
while(...)
{
  draw();
  input();
  move_units();
  pathfind();
}
where pathfind() is a small number of steps in a pathfinding
algorithm.  Warcraft II, for instance, uses a pathfinding algorithm
that takes small steps from the unit's current location.
