nn::os::BlockingQueue Class

class BlockingQueue : private nn::os::detail::BlockingQueueBase

Class for handling blocking queues.

A blocking queue is a messaging mechanism that provides the ability to synchronize threads safely.

The number of elements that can be placed in the queue is limited by the size of the buffer provided during initialization. Attempting to add additional elements to the queue beyond this limit will cause the thread to block. Similarly, attempting to retrieve an element from an empty queue will cause the thread to block.

Blocking queues have the same features as what have up until now been referred to as "message queues."

Because CriticalSection sections are used internally for thread synchronization, deadlocks may occur in situations that could lead to priority inversion or other scheduling issues. When such a possibility exists, use SafeBlockingQueue instead.
