Re: using std::deque in multiple threads

I have a thread that listens on a message queue and populates a
std::deque with events from that message queue, but only holds the
latest 100.
In my main thread, I want to populate a listbox with the information
from that deque. So, it ends up being that one thread can add/remove
items from the deque while another thread is trying to iterate through
them. How can I make this thread-safe?

Thanks,

The code looks a bit like this:

std::deque<MESSAGE_TYPE> m_dequeMessages;

CMyClass::MessageThread()
{
  //...
  while (ReadMsgQueue(hMsgQueue, &msg,...))
  {

    m_dequeMessages.push_back(msg);
    if(m_dequeMessages.size() > 100)
      m_dequeMessages.pop_front();

  }
  //...
}

CListCtrl c_MyList;

CDlgClass::PopulateList()
{

  for (vector::iterator i = m_dequeMessages.begin(),
        i != m_vMessages.end()
        ++i)
  {
    c_MyList.InsertItem(0, i->Message);
  }

}
