C++深拷贝和浅拷贝构造函数

深拷贝：内存拷贝，每块内存有不同的指针

浅拷贝：指针的拷贝，拷贝之后指向同一块内存

typedef struct {
  int index;      //对应APP接口协议中的索引号
  int iRegThrdCnt;  //注册的线程个数
}TMsgGather;

class CMsgGather
{
public:
  CMsgGather();
  ~CMsgGather();

  CMsgGather(const CMsgGather &msgGather); //深拷贝构造

private:
  TMsgGather msgGather[128];
};

CMsgGather::CMsgGather()
{
  printf("CMsgGather::CMsgGather\n");
}

CMsgGather::~CMsgGather()
{
  printf("CMsgGather::~CMsgGather\n");
}

CMsgGather::CMsgGather(const CMsgGather &msgGather)
{
  printf("CMsgGather::CMsgGather(const CMsgGather &msgGather)\n");
}      

#include "MsgGather.h"

void test(CMsgGather msgGather)
{
  printf("test(CMsgGather msgGather)\n");
}

int main(int argc, char *argv[])
{
  try
  {
    CMsgGather msgGather;
    test(msgGather);
  }
  catch (const std::exception&)
  {

  }
}
