Usage
Basic Lock and Unlock Example
require 'tlopo/futex'
# Initialize the lock with a path to a lock file
lock = Tlopo::Futex.new('/tmp/my_lock_file')
# Lock, execute critical code, then release
lock.lock
# Critical section code goes here
lock.release
Checking Lock Status
You can check if the lock is currently active:
if lock.locked?
puts "Resource is locked by another process"
else
lock.lock
# Critical section code
lock.release
end

for Automatic Locking
The synchronize
method locks and releases automatically, ensuring that the lock is properly released even if an error occurs.
lock.synchronize do
# Critical section code that needs exclusive access
end
