C++ (Cpp) StateStackPtr::get Examples

Example #1

File: thread.cpp Project: Kozlov-Sergey-Aleksandrovitch/Wizard-Junior-chess

void ThreadPool::start_thinking(const Position& pos, const LimitsType& limits, StateStackPtr& states) {

  wait_for_think_finished();

  SearchTime = Time::now(); // As early as possible

  Signals.stopOnPonderhit = Signals.firstRootMove = false;
  Signals.stop = Signals.failedLowAtRoot = false;

  RootMoves.clear();
  RootPos = pos;
  Limits = limits;
  if (states.get()) // If we don't set a new position, preserve current state
  {
      SetupStates = std::move(states); // Ownership transfer here
      assert(!states.get());
  }

  for (const ExtMove& ms : MoveList<LEGAL>(pos))
      if (   limits.searchmoves.empty()
          || std::count(limits.searchmoves.begin(), limits.searchmoves.end(), ms.move))
          RootMoves.push_back(RootMove(ms.move));

  main()->thinking = true;
  main()->notify_one(); // Starts main thread
}
