在wait_for 返回时,lock.owns_lock() 是true,并且调用线程会锁定 lock.mutex()。如果无法满足这些后条件[1],那么就会调用 std::terminate。 如果满足以下任意条件,那么行为未定义: lock.owns_lock() 是false。 调用线程没有锁定 lock.mutex()。 在有其他线程也在 *this 上等待的情况下,那些线程在 *...
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,或发生虚假唤醒。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)等价于returnwait_until(lock,std::chrono::steady_clock::now()+rel_time, std::move(pred));。

概述:cpp在编译链接过程中,会产生很多种类的中间文件和结果文件,这些个文件是否达到预期目标,都是要进行测试的,还有当运行时出现问题,也是需要进行检测的。这里就是一些linux下帮助测试和调试的命令。除了linux系统,在windows中也可以通过安装mingw来获取各种需要的命令,它们的行为是类似的。

AMQP-CPP is a C++ library for communicating with a RabbitMQ message broker. The library can be used to parse incoming data from a RabbitMQ server, and to generate frames that can be sent to a RabbitMQ server. This library has a layered architecture, and allows you - if you like - to...
