class, the abstract base class for event wait handles, mutexes, and semaphores, which enables waiting for multiple synchronization events 类,它是事件等待句柄、mutex和信号量的抽象基类,可以用于等待多个同步事件。
in certain situations, they can result in a transaction spanning multiple synchronization domains that is, allowing parallelism with a transaction 在某些情况下,它们会导致事务跨越多个同步域(即允许与事务平行)。
in certain situations, they can result in a transaction spanning multiple synchronization domainsthat is, they allow parallelism with another transaction, causing a deadlock condition 事务。在某些情况下,这些事务可能导致一个事务跨多个同步域;也就是说,它们可能与其他事务并行,这会导致出现死锁情况。
