wait_for导致当前线程阻塞,直至条件变量被通知,超过指定的时长,发生或虚假唤醒。可以提供pred以检测虚假唤醒。 1)等价于returnwait_until(lock,std::chrono::steady_clock::now()+rel_time);。 2,3)等待特定条件为真,可用于忽略虚假唤醒。 2)等价于returnwait_until(lock

现在神秘是为什么非谓词版本 wait_for 遭受虚假的唤醒问题。我的猜测是,当多线程运行时(-pthread) 用来。也许 condition_variable 当POSIX线程库链接时具有不同的行为或不同的实现。智能推荐C# 应用Excel条件格式(一) Excel中的条件格式功能是个十分强大且方便的功能,通过对使用条件格式功能可以在很大程度上改进表格...
