What is the unique lock usage in programming?

Unique lock usage refers to a locking mechanism that allows only one thread to access a resource at a time, ensuring data integrity.

Can you explain how it differs from shared locks?

Sure! A unique lock prevents any other thread from accessing the resource, while a shared lock allows multiple threads to read the resource simultaneously.

When should I use a unique lock?

You should use a unique lock when you need to modify a resource and want to prevent other threads from accessing it during that time.

Are there any performance implications?

Yes, using unique locks can lead to performance bottlenecks if overused, as they can cause threads to wait for access.
