Expand description

Additional methods for mutexes which support fair unlocking.

Fair unlocking means that a lock is handed directly over to the next waiting thread if there is one, without giving other threads the opportunity to “steal” the lock in the meantime. This is typically slower than unfair unlocking, but may be necessary in certain circumstances.

Required Methods§

Unlocks this mutex using a fair unlock protocol.

Provided Methods§

Temporarily yields the mutex to a waiting thread if there is one.

This method is functionally equivalent to calling unlock_fair followed by lock, however it can be much more efficient in the case where there are no waiting threads.
