Re: using std::deque in multiple threads
Create a CRITICAL_SECTION object cs and initialize it
Then see code inserted in-line...
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
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?
The code looks a bit like this:
while (ReadMsgQueue(hMsgQueue, &msg,...))
if(m_dequeMessages.size() > 100)
for (vector::iterator i = m_dequeMessages.begin(),
i != m_vMessages.end()
This will cause one thread to wait (at Enter...) if the other thread is
within the critical section.
