用ACE实现的生产者和消费者模式

#include "ace/Log_Msg.h"#include "ace/Task.h"#include "ace/OS.h"#include "ace/Message_Block.h"#include <stdio.h>#include <string.h>typedef struct User_{int len;char buffer[20];int count;} User;//The Consumer Task.class Consumer:public ACE_Task<ACE_MT_SYNCH>{public:int open(void*){ACE_DEBUG((LM_DEBUG, "(%t) Consumer task opened /n"));//Activate the Taskactivate(THR_NEW_LWP,1);return 0;}//The Service Processing routineint svc(void){//Get ready to receive message from ProducerACE_Message_Block * mb =0;int count = 0;do{mb=0;//Get message from underlying queuegetq(mb);User *user = (User*)mb->rd_ptr();count = user->count;ACE_DEBUG((LM_DEBUG,"(%t)Got message: %s,%d,%d from remote task/n",user->buffer,user->len,user->count));delete user;mb->release();}while(count < 10);return 0;}int close(u_long){ACE_DEBUG((LM_DEBUG,"Consumer closes down /n"));return 0;}};class Producer : public ACE_Task<ACE_MT_SYNCH>{public:Producer(Consumer * consumer):consumer_(consumer), count(0){//mb_=new ACE_Message_Block((char*)&data_,sizeof(data_));}int open(void*){ACE_DEBUG((LM_DEBUG, "(%t) Producer task opened /n"));//Activate the Taskactivate(THR_NEW_LWP,1);return 0;}//The Service Processing routineint svc(void){while(count<11){//Send message to consumerACE_DEBUG((LM_DEBUG,"(%t)Sending message: %d to remote task/n",count));User *user = new User();sprintf(user->buffer,"hello %d",count);user->len = strlen(user->buffer);user->count = count;mb_=new ACE_Message_Block((char*)user,sizeof(User));consumer_->putq(mb_);//Go to sleep for a sec.ACE_OS::sleep(1);count++;}return 0;}int close(u_long){ACE_DEBUG((LM_DEBUG,"Producer closes down /n"));return 0;}private:int count;Consumer * consumer_;ACE_Message_Block * mb_;};int main(int argc, char * argv[]){Consumer * consumer = new Consumer;Producer * producer = new Producer(consumer);producer->open(0);consumer->open(0);//Wait for all the tasks to exit.ACE_Thread_Manager::instance()->wait();ACE_OS::system("pause");delete producer;delete consumer;return 0;} 

 

运行结果如下图：
