ReentrantLock

ReentrantLock()

Creates a reentrant lock. The same task can acquire the lock as many times as required. Each lock must be matched with an unlock.

Examples

using Base.Threads

# Create a reentrant lock
lock = ReentrantLock()

# Acquire the lock
lock(lock)

# Perform some operations while holding the lock

# Release the lock
unlock(lock)

In the code example above, we demonstrate the usage of the ReentrantLock function in Julia. Here's a breakdown of the example:

1. We first import the Base.Threads module to access the ReentrantLock function.

2. We create a reentrant lock by calling the ReentrantLock() function and assigning it to the variable lock.

3. To acquire the lock, we use the lock(lock) syntax. This allows the same task to acquire the lock multiple times without deadlock.

4. Inside the lock, you can perform any operations or critical sections that require exclusive access.

5. Once you're done with the locked section, you release the lock by calling unlock(lock).

It's important to note that each lock call should be matched with an unlock call to ensure proper synchronization and avoid potential deadlocks.

Remember, reentrant locks allow the same task to acquire the lock multiple times, which can be useful in certain scenarios.
