What are file locking techniques and how do they work?

File locking techniques are methods used to control access to files in a computing environment, ensuring that only one process can modify a file at a time.

Why is file locking important in multi-user systems?

File locking is crucial in multi-user systems to prevent data corruption and ensure data integrity when multiple users attempt to access or modify the same file.

Can you explain the difference between advisory and mandatory locking?

Advisory locking allows processes to voluntarily check for locks and cooperate, while mandatory locking enforces restrictions at the system level, preventing access without the proper locks.

What are some common file locking mechanisms used in programming?

Common file locking mechanisms include POSIX locks, flock, and Windows file locks, each with its own implementation and use cases.
