linux线程（二）内存释放

 1 //case 1：创建线程时设置为Detach，即unjoinable
 2 pthread_t tid;
 3 pthread_attr_t attr;
 4 pthread_attr_init(&attr);
 5 pthread_attr_setdetachstate(&attr,PTHREAD_CREATE_DETACHED); 
 6 pthread_create(&tid, &attr, (void *)&thread_function, NULL); 
 7 
 8 //case 2：在线程中调用pthread_detach
 9 void thread_function(void *p)
10 {
11     pthread_detach(pthread_self());
12 }
13 
14 //case 3: 在创建线程后调用pthread_detach
15 pthread_create(&tid, NULL, (void *)&thread_function, NULL); 
16 pthread_detach(tid);

1 pthread_create(&tid, NULL, (void *)&thread_function, NULL); 
2 pthread_join(thread_id, NULL);
