这种方式实现单例不错：
#ifndef __IPERF_COLLECTION_H__
#define __IPERF_COLLECTION_H__
#include <map>
#include <pthread.h>
#include "macros.h"
using namespace std;
typedef void ( * port_performance_calback_t ) ( void * data ) ;
template<typename T>
class Singleton{
public:
static T& get_instance(){
static T instance;
return instance;
}
virtual ~Singleton(){
std::cout<<"destructor called!"<<std::endl;
}
Singleton(const Singleton&)=delete;
Singleton& operator =(const Singleton&)=delete;
protected:
Singleton(){
std::cout<<"constructor called!"<<std::endl;
}
};
class IperfCollection:public Singleton<IperfCollection> {
friend class Singleton<IperfCollection>;
public:
int Init(port_performance_calback_t cb);
private:
int createFifo();
int stringParsing(string str,int port);
static void *iperfDataCollection(void *data);
IperfCollection():_callback(NULL){}
~IperfCollection(){}
pthread_t _threadId;
port_performance_calback_t _callback;
map<int,string> _portFifo;
map<int,int> _portFd;
};
#endif
