What are advanced mutex usage techniques in C++?

What are advanced mutex usage techniques in C++?

Advanced mutex usage in C++ includes techniques like recursive mutexes, timed mutexes, and using unique locks for better resource management.

Can you explain how a recursive mutex works?

A recursive mutex allows the same thread to lock it multiple times without causing a deadlock. Each lock must be matched with an unlock.

What are the advantages of using timed mutexes?

Timed mutexes allow a thread to attempt to lock a mutex for a specified duration, preventing indefinite blocking and improving responsiveness.

How do unique locks differ from regular locks?

Unique locks provide more flexibility than regular locks, allowing for deferred locking, timed locking, and automatic unlocking when going out of scope.

Are there any performance considerations when using mutexes?

Yes, excessive locking can lead to contention and performance bottlenecks. It's important to minimize lock duration and use them judiciously.
