}
int main()
{
//定义pthread_attr_t类型的变量pthread_attr_t attr;
//初始化attr变量pthread_attr_init(&attr);
//设置attr为分离属性pthread_attr_setdetachstate(&attr,PTHREAD_CREATE_DETACHED);//int pthread_create(pthread_t *thread, const pthread_attr_t *attr,// void *(*start_routine) (void *), void *arg);pthread_t thread;int ret=pthread_create(&thread,&attr,mythread,NULL);if(ret!=0){printf("pthread_create error:[%s]\n",strerror(ret));return -1;}
//验证子线程是否为分离状态，如果是分离状态，pthread_join不会阻塞，立即打印错误ret=pthread_join(thread,NULL);if(ret!=0){printf("prhread_join error:[%s]\n",strerror(ret));}printf("father thread id==[%ld]\n",pthread_self());
//释放线程属性pthread_attr_destroy(&attr);
//防止主线程结束，子线程还没有执行sleep(1);
}

结果：
