inc_count(): thread 1, count = 13, unlocking mutex
inc_count(): thread 0, count = 14, unlocking mutex
inc_count(): thread 1, count = 15, unlocking mutex
条件变量示例 ✓输出结果
inc_count(): thread 0, count = 5, unlocking mutex inc_count(): thread 0, count = 6, unlocking mutex inc_count(): thread 1, count = 7, unlocking mutex
生产者/消费者问题—PV原语操作
生产者/消费者问题 ✓采用多线程技术解决生产者/消费者问题 ➢也称有界缓冲区问题 •多个生产者线程向缓冲区中写数据 •多个消费者线程从缓冲区中读取数据 ➢生产者线程和消费者线程必须满足 •生产者写入缓冲区的数目不能超过缓冲区容量 •消费者读取的数目不能超过生产者写入的数目
