mutex类型有四种 PTHREAD_MUTEX_NORMAL PTHREAD_MUTEX_ERRORCHECK PTHREAD_MUTEX_RECURSIVE PTHREAD_MUTEX_DEFAULT 1.mutex初始化 1 2 3 4 5 6 var mutex = pthread_mutex_t() var attr: pthread_mutexattr_t = pthread_mutexattr_t() pthread_mutexattr_init(&attr) pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_RECURSIVE) pthread_mutex_init(&mutex, &attr) 2.mutex使用 1 2 3 pthread_mutex_trylock(&mutex) //执行代码块 pthread_mutex_unlock(&mutex) 3.mut
