WebbThe Thread Pool pattern helps to save resources in a multithreaded application and to contain the parallelism in certain predefined limits. When we use a thread pool, we write our concurrent code in the form of parallel tasks and submit them for execution to an instance of a thread pool. WebbThe ThreadPool class extends the Pool class and therefore has the same API. Although the ThreadPool class is in the multiprocessing module it offers thread-based concurrency. Recall that a thread is a thread of execution. Each thread belongs to a process and can share memory (state and data) with other threads in the same process. grady hospital appointmentWebb2 juni 2024 · 基于C++11的线程池 (threadpool),简洁且可以带任意多的参数咳咳。 C++11 加入了线程库，从此告别了标准库不支持并发的历史。然而 c++ 对于多线程的支持还是比较低级，稍微高级一点的用法都需要自己去实现，譬如线程池、信号量等。线程池 (thread pool)这个东西，在面试上多次被问到，一般的回答都是：“管理一个任务队列，一个线 … chimney wall vent
