Overall the code looks functional to me Everytime you pop it will wait on the condition variable if the queue is empty Everytime you push a notification will be sent to any If the intention is to have a thread safe queue then passing pointers in and out is definitely not the way to go The problem is with object ownership Even if your thread

Although some parts of the interface in the OP s queue are very suspect the general idea of a simple thread safe queue backed by std condition variable std mutex and By default std queue is not thread safe Multiple threads accessing the same std queue object concurrently can lead to race conditions and undefined behavior If you need to use queues in a multi threaded

Concurrency support library edit C includes built in support for threads atomic operations mutual exclusion condition variables and futures Threads enable The following thread safety rules apply to all classes in the C Standard Library this includes shared ptr as described below Stronger guarantees are sometimes provided for example

The thread pool needs an appropriate queue to hold tasks and their parameters hence the queue should be thread safe The execution of the thread pool will only stop when SafeQueue This class is a multi producer multi consumer queue It offers both blocking and non blocking consuming as well while producing is always blocking The capacity is

This requires waking up the threads that are blocked on cond var wait and having some way to signal that they should exit their loop either using a separate flag or by A C library that provides utilities for managing thread safe operations This library is designed to simplify concurrent programming by offering easy to use and robust thread safe
