我有两个处,即:<代码>A和B。 两者都取决于对方,因此,如果一次坠毁和重新启动,则必须立即重新开始。

我已撰写了一个监测方案,分别启动和监测这两个服务,该方案一旦坠毁,可重新启动一个服务。

我想改进监测方案,以便当发现一个服务已经失事时,它将获得另一个服务信息数据库,杀死它。

The monitor process will spawn the two children using fork(2), right? If so, the parent will get back the child PID, which it can save in a variable for each child.

在对这两个过程进行监视之后,母子监测员只能坐在一间休息室里,等待waitpid(2)。 借助正确的选择,这一呼吁可以阻止,直到一名儿童终止,因为当时你回到了儿童保护局及其退出地位。 根据这一点,你可以做以下工作:,技能(2)

请注意,在杀害第二个儿童之后,您的下一次等待呼吁将退回儿童发展论坛,而不是新的儿童之友之一。 因此,你需要对照 两个孩子的登记,如果他们不匹配,就会忽视。
