Reentrant locks are synchronization primitives that allow a thread to acquire the same lock multiple times without causing a deadlock.
How do they work in a multithreaded environment?
In a multithreaded environment, reentrant locks allow a thread to enter a critical section multiple times, ensuring that it can safely execute code without blocking itself.
What are the advantages of using reentrant locks?
The main advantages include preventing deadlocks, allowing recursive locking, and simplifying code that requires multiple entries into a critical section.
Are there any downsides to using them?
