What are the types of locks in threading?

What are the different types of locks used in threading?

In threading, the main types of locks are mutexes, spinlocks, read-write locks, and recursive locks. Would you like to know more about any specific type?

Can you explain mutexes?

A mutex, or mutual exclusion lock, allows only one thread to access a resource at a time, preventing race conditions.

What about spinlocks?

Spinlocks are a type of lock where a thread repeatedly checks if the lock is available, which can be efficient for short waits.

Are read-write locks different from regular locks?

Yes, read-write locks allow multiple threads to read a resource simultaneously but only one to write, enhancing concurrency.

How do recursive locks work?

Recursive locks allow the same thread to acquire the lock multiple times without causing a deadlock, keeping track of the number of acquisitions.
