How does C++11 ensure thread safety in std::priority_queue?

C++11's std::priority_queue is not inherently thread-safe. You need to manage synchronization yourself.

What synchronization mechanisms can I use to make it thread-safe?

You can use mutexes or locks to protect access to the priority queue when multiple threads are involved.

Can you provide a code example of using a mutex with std::priority_queue?

Sure! Here's a simple example:

#include <queue>
#include <mutex>
#include <thread>

std::priority_queue<int> pq;
std::mutex mtx;

void threadSafePush(int value) {
    std::lock_guard<std::mutex> lock(mtx);
    pq.push(value);
}
