File Locking
SMB (Server Message Block) client opens a file
– Requests “deny mode” to be set
• deny_none
• deny_read
•deny_write
•deny_al
•etc
– This specifies what action should be allowed by anyone else
trying to open the same file
Example
– If deny_read is placed on the file, then any attempt to open the file for reading
should fail
