然后,我们可以编写函数来初始化线程池并添加任务,如下所示: ```c void threadpool_init(threadpool_t *pool, int num_threads) { pool->num_threads = num_threads; pool->running = 1; pthread_mutex_init(&pool->lock, NULL); pthread_cond_init(&pool->cond, NULL); pool->threads = (pthread_t...
本项目线程池功能分以下几个函数去实现: > threadpool.init(isize_t num);设置线程的数量 > threadpool::get(TaskFuncPtr& task);读取任务队列中的任务 > threadpool::run();通过get()读取任务并执行 > threadpool.start(); 启动线程池,并通过run()执行任务 > threadpool.exec();封装任务到任务队列中 ...
/* 初始化互斥锁 */ pthread_mutex_init(&lock,NULL); /* 断言线程池创建成功 */ assert((pool=threadpool_create(THREAD,QUEUE,0))!=NULL); fprintf(stderr,"Pool started with %d threads and " "queue size of %d\n",THREAD,QUEUE); /* 只要任务队列还没满,就一直添加 */ while(threadpool_add...
1、pthread_once pthread_once(&ponce_, &Singleton::init); 保证init函数只被调用一次,即只初始化一个对象。在init内部 value_ = new T(); 2、atexit ::atexit(destroy); 在init 函数内注册destroy,在程序结束时会调用destroy,在destroy内部delete value_; 3、typedef char T_must_be_complete_type[sizeof...
static void init(Pool& pool, size_t const worker_count) { pool.resize(worker_count); } static void init(Pool& pool, size_t const worker_count) { pool.resize(worker_count); } //pool_core的resize函数 这个函数有点长,主要是做动态配置线程个数的逻辑操作,create_and_attach也是在这里调用的。
pthread_mutex_init(&lock, NULL);/* 断言线程池创建成功 */ assert((pool = threadpool_create(THREAD, QUEUE,0)) != NULL);fprintf(stderr,"Pool started with %d threads and ""queue size of %d\n", THREAD, QUEUE);/* 只要任务队列还没满,就一直添加 */while(threadpool_add(pool, &dummy_tas...
