在使用wait_for_completion()的_timeout()或_killable()/_interruptible()变体时,应特别小心,因为必须确保在所有相关活动(complete()或reinit_completion())发生之前不会发生内存释放,即使这些等待函数由于超时或信号触发而提前返回。 通过调用init_completion()来初始化动态分配的完成对象: init_completion(&dynamic_obj...
(1) 进程在等待完成时处于不可中断状态,若使用wait_for_completion_interruptible表示可中断,如果进程被中断,则返回-ERESTARTSYS,否则返回0; (2) wait_for_completion_timeout表示等待事件的发生,并且提供超时设置,如果超过了这一设置,则取消等待,可防止无限等待;如果在超时之前完成则返回剩余时间,否则返回0。 (3) w...
try_wait_for_completion函数功能描述:此函数用于尝试无阻塞的消耗一个completion,与函数wait_for_completion( )不同,wait_for_completion( )是有阻塞的。如果传入的参数x的done字段的值为0,此次尝试失败;如果传入的参数的x的done字段的值为1,此次尝试成功,并且字段d

A value describing the outcome of waiting forexpectations. Discussion Expectations can only appear in the array once. The test discards the waiter when the wait completes. In Objective-C code, you might use an expectation to wait on a call to an interface that uses a completion handler to re...
a. 继承关系 wait_timeout在session和global级别分别继承那个参数? b. 生效参数 在交互式会话和程序访问的非交互模式两种情况下到底哪个参数决定了空闲会话的存活时间? 二 参数介绍 首先说明两个关键词通过MySQL客户端连接db的是交互会话,通过jdbc等程序连接db的是非交互会话。
