Mutex Types and Locking Methods
Explore the various mutex types in C++ including recursive_mutex, timed_mutex, shared_timed_mutex, and shared_mutex. Understand their locking methods such as try_lock, try_lock_for, and try_lock_until. Learn how these mutexes solve concurrency problems and how to implement thread-safe locks using lock guards and unique locks, preparing you to manage shared data effectively.

C++ has five different mutexes that can lock recursively (i.e., multiple layers of locking), tentative with and without time constraints.
| Method | mutex | recursive_mutex | timed_mutex | recursive_timed_mutex | shared_timed_mutex |

m.lock |
yes | yes | yes | yes | yes |
m.unlock |
yes | yes | yes | yes | yes |
m.try_lock |
