下面的两个线程共享一个消息队列，一个用来放整数到队列，一个从队列里取消息出来。此程序在控制台不停的输出递增数字，主要是内存不会泄露

用到了多线程、ACE_Message_Queue、ACE_Message_Block、ACE_Thread_Manager::instance()->spawn等

#include <iostream>
using namespace std;
#include "boost/lexical_cast.hpp"
using namespace boost;
#include "ace/Thread_Manager.h" 
#include "ace/Message_Queue.h"

void* create_vairous_record(void* ace_message_queue);

void* get_vairous_record(void* ace_message_queue);

int ACE_TMAIN (int argc, ACE_TCHAR *argv[]) 
{

	ACE_Message_Queue<ACE_MT_SYNCH>* various_record_queue = new ACE_Message_Queue<ACE_MT_SYNCH>;

	ACE_Thread_Manager::instance()->spawn(

		various_record_queue,

	ACE_Thread_Manager::instance()->spawn(
		ACE_THR_FUNC(get_vairous_record),

	ACE_Thread_Manager::instance()->wait();

	return 0;
}

	int i=0;
	while (i<10000000)
	{
		ACE_Message_Block* mbl = new ACE_Message_Block(10);//在这里创建消息
		string temp = lexical_cast<string>(++i);
		mbl->copy(temp.c_str());
		p_queue->enqueue_tail(mbl);//消息被放到队列中（用指针引用消息实体）
	}
	return nullptr;
}
