Editing File locking (section)

== In AmigaOS ==
In [[AmigaOS]], a lock on a file (or directory) can be acquired using the <code>Lock</code> function (in the <code>dos.library</code>). A lock can be shared (other processes can read the file/directory, but can't modify or delete it), or exclusive so that only the process which successfully acquires the lock can access or modify the object. The lock is on the whole object and not part of it. The lock must be released with the <code>UnLock</code> function: unlike in Unix, the operating system does not implicitly unlock the object when the process terminates.
