Name

queuing_mutex Class — Class that models the Mutex Concept that is fair and scalable.

Synopsis

#include "tbb/queuing_mutex.h"

class queuing_mutex;

Description

A queuing_mutex models the Mutex Concept. A queuing_mutex is scalable, in the sense that if a task has to wait to acquire the mutex, it spins on its own local cache line. A queuing_ mutex is fair, in that tasks acquire the lock in the order they requested it, even if they are later suspended. A queuing_mutex is not reentrant.

The current implementation does busy-waiting, so using a queuing_mutex may degrade system performance if the wait is long.
