unlock cookie problem

[xi brian]

"Releases the lock on a record. Cookie must be the cookie
returned when the record was locked; otherwise throws SecurityException.

public void unlock(long recNo, long cookie)
throws SecurityException;"

does the above means that recNo and cookie must be equal? otherwise, throws SecurityException

Method documentation contains: Releases the lock on a record. Cookie must be the cookie returned when the record was locked; otherwise throws SecurityException.?

Throw SecurityException if you use other than returned using the lock method.
