首先，互斥量这种线程相关的内容是平台相关的，我假设你用的是windows平台开发。
其次，说明一下我的开发环境，vs2008，控制台程序，空的工程。
最后给你贴代码，分文件来看。
===头文件QueueNode.h===
===你需要的节点数据可能不是整数，只要将typedef int QUEUEDATA这一句的int换成你想要的类型即可，但要注意，这个类型必须实现赋值操作符重载，相等比较操作符重载，以及复制构造函数===
#ifndef _QUEUE_NODE_H_
#define _QUEUE_NODE_H_
typedef int QUEUEDATA;
typedef struct node
{
QUEUEDATA data;
node* m_pNext;
}QUEUENODE;
#endif
===队列头文件Queue.h，有平台相关内容，请注意===
#ifndef _QUEUE_H_
#define _QUEUE_H_
#include "QueueNode.h"
#include <Windows.h>
class ThreadSafeQueue
{
public:
ThreadSafeQueue();
virtual ~ThreadSafeQueue();
bool InitQueue();
void EnQueue(const QUEUEDATA& data);
void DeQueue();
void Clear();
const QUEUENODE* Find(const QUEUEDATA& data) const;
void Print();
protected:
HANDLE m_hMutex;
QUEUENODE* m_pQueueHead;
};
#endif
===队列函数实现文件Queue.cpp===
#include "Queue.h"
#include <iostream>
ThreadSafeQueue::ThreadSafeQueue()
{
m_pQueueHead = new QUEUENODE;
m_pQueueHead->m_pNext = 0;
}
ThreadSafeQueue::~ThreadSafeQueue()
{
Clear();
delete m_pQueueHead;
CloseHandle(m_hMutex);
}
bool ThreadSafeQueue::InitQueue()
{
m_hMutex = CreateMutex(0, FALSE, 0);
return (m_hMutex!=0);
}
void ThreadSafeQueue::EnQueue(const QUEUEDATA& data)
{
WaitForSingleObject(m_hMutex, INFINITE);
QUEUENODE* pNode = new QUEUENODE;
pNode->data = data;
pNode->m_pNext = 0;
QUEUENODE* pTemp = m_pQueueHead;
while (pTemp->m_pNext != 0)
{
pTemp = pTemp->m_pNext;
}
pTemp->m_pNext = pNode;
ReleaseMutex(m_hMutex);
}
void ThreadSafeQueue::DeQueue()
{
WaitForSingleObject(m_hMutex, INFINITE);
QUEUENODE* pNode = m_pQueueHead->m_pNext;
if (pNode != 0)
{
m_pQueueHead->m_pNext = pNode->m_pNext;
delete pNode;
pNode = 0;
}
ReleaseMutex(m_hMutex);
}
const QUEUENODE* ThreadSafeQueue::Find(const QUEUEDATA& data) const
{
WaitForSingleObject(m_hMutex, INFINITE);
QUEUENODE* pNode = m_pQueueHead->m_pNext;
while (pNode != 0)
{
if (pNode->data == data)
{
break;
}
pNode = pNode->m_pNext;
}
return pNode;
ReleaseMutex(m_hMutex);
}
void ThreadSafeQueue::Clear()
{
WaitForSingleObject(m_hMutex, INFINITE);
QUEUENODE* pNode = m_pQueueHead->m_pNext;
QUEUENODE* pTemp = 0;
while (pNode != 0)
{
pTemp = pNode->m_pNext;
delete pNode;
pNode = pTemp;
}
m_pQueueHead->m_pNext = 0;
ReleaseMutex(m_hMutex);
}
void ThreadSafeQueue::Print()
{
WaitForSingleObject(m_hMutex, INFINITE);
QUEUENODE* pNode = m_pQueueHead->m_pNext;
while (pNode != 0)
{
std::cout << pNode->data << "\t";
pNode = pNode->m_pNext;
}
std::cout << std::endl;
ReleaseMutex(m_hMutex);
}
===测试代码文件main.cpp，包含了测试用可执行程序，两个操作queue的线程，需要说明的是，我本来打算用WaitMultipleObjects函数来等待两个线程都结束，但是没搞清楚是什么问题没有卡住，不打算继续纠缠它了，所以让主线程Sleep了5秒钟===
#include "Queue.h"
#include <iostream>
DWORD WINAPI HandleQueue(void* pParam);
DWORD WINAPI HandleQueue2(void* pParam);
int main()
{
ThreadSafeQueue queue;
queue.InitQueue();
HANDLE hThread[2] = {0};
DWORD threadID = 0;
hThread[0] = CreateThread(NULL, 0, HandleQueue, (void*)(&queue), NULL, &threadID);
hThread[0] = CreateThread(NULL, 0, HandleQueue2, (void*)(&queue), NULL, &threadID);
//WaitForMultipleObjects(2, hThread, TRUE, INFINITE);
Sleep(5000);
queue.Print();
queue.Clear();
return 0;
}
DWORD WINAPI HandleQueue(void* pParam)
{
ThreadSafeQueue* pQueue = reinterpret_cast<ThreadSafeQueue*>(pParam);
for (int i = 0; i < 100; i++)
{
std::cout << "HandleQueue EnQueue" << std::endl;
pQueue->EnQueue(i);
}
for (int i = 0; i < 50; i++)
{
std::cout << "HandleQueue DeQueue" << std::endl;
pQueue->DeQueue();
}
return 0;
}
DWORD WINAPI HandleQueue2(void* pParam)
{
ThreadSafeQueue* pQueue = reinterpret_cast<ThreadSafeQueue*>(pParam);
for (int i = 0; i < 100; i++)
{
std::cout << "HandleQueue2 EnQueue" << std::endl;
pQueue->EnQueue(i+100);
}
for (int i = 0; i < 50; i++)
{
std::cout << "HandleQueue2 DeQueue" << std::endl;
pQueue->DeQueue();
}
return 0;
}
