在C++11之前,C++标准库并没有提供线程支持,开发者需要依赖于操作系统提供的API(如Windows的CreateThread函数或者POSIX的pthread_create函数)来创建和管理线程。这种方式的问题在于,不同的操作系统提供的线程API可能会有所不同,这就导致了代码的可移植性问题。
4.1.2 Linux的pthread库 在Linux平台上,pthread库是处理线程的主要方式。pthread提供了广泛的线程管理功能,包括设置线程堆栈大小、线程分离、同步机制等。它是一种更底层的线程管理方法,适用于需要更细致控制线程的场景。 4.2 使用高级线程管理工具 4.2.1std::async和std::future ...
