line at fetch and remains until the next fetch or the cursor closes, whichever occurs first. The next time the fetch occurs, the server acquires a scroll lock for the row in the new fetch and releases the last scroll lock to fetch rows. A scroll lock is independent of the transaction lock and can be persisted after a commit or rollback operation. If the option to close the cursor at commit is off, the commit statement does not close any open cursors, and the scroll lock is persisted to the comm

to disambiguate between static and static method parameters (similar to what we did when we processed the instance properties and instance method parameters earlier).In general, any unqualified method and property name will come from another type-level method and property in this class. A type method can invoke the name of another type method in this class without prefixing the method name with the type name. Similarly, struct and enum type methods can also access static properties directly fro

single player, but it can also store Game Information of multiple players on the same device. At the beginning of the game, all game levels (except level 1) were locked. Each time a player completes a level, it unlocks all players on the device. The LevelTracker struct uses static attributes and methods to monitor which level of the game has been unlocked. It also monitors the current level of each player. struct LevelTracker { static var highes

. This locking strategy guarantees the fairness of resource allocation. pthread_mutex_recursive_np, nested locks allow the same thread to be successfully acquired multiple times for the same lock, and unlocked by multiple unlock. If it is a different thread request, re-competes when the lock line threads unlocked. PTHREAD_MUTEX_ERRORCHECK_NP, checks the wrong lock, returns EDEADLK if the same thread
