What is file locking in multi-user systems?
File locking is a mechanism that restricts access to a file by multiple users to prevent conflicts and data corruption.
How does file locking work in practice?
In practice, when a user opens a file, the system can lock it, preventing others from making changes until it's unlocked.
What are the different types of file locks?
There are mainly two types: exclusive locks, which prevent others from accessing the file, and shared locks, which allow read access.
What happens if a user forgets to unlock a file?
If a user forgets to unlock a file, it can lead to access issues for others, and some systems may have timeout mechanisms to release the lock.
Can file locking lead to deadlocks?
Yes, improper management of file locks can lead to deadlocks, where two or more processes are waiting indefinitely for each other to release locks.
