STL list使用心得

 1.list排序

 

struct NOTIFY_RECEIVE_HISTORY_GameInfo_PACKET
{
 char   Gmcode[4] ; //游戏编号
 char   round[16];   //期号
 uint64 Time2 ;     //开始时间
 uint32 resbits;     //该期输赢结果，玩法对应位1则赢。玩法值见附录
 uint16 sum;         //总和
 char   reslst[20];  //结果列表

 

 NOTIFY_RECEIVE_HISTORY_GameInfo_PACKET()
 {
  memset(this,0,sizeof(NOTIFY_RECEIVE_HISTORY_GameInfo_PACKET));
 }

};

 

class SortHistoryGameInfo_Cmp  //最基本的排序函数
{
public:
 bool operator()(NOTIFY_RECEIVE_HISTORY_GameInfo_PACKET& gameinfo1,NOTIFY_RECEIVE_HISTORY_GameInfo_PACKET& gameinfo2) const
 {
  if ( strlen(gameinfo1.round) == 0)
   return FALSE;

  if ( strcmp(gameinfo1.round , gameinfo2.round) > 0 )
   return TRUE;
  else
   return FALSE;
 }
};

 

 

SortHistoryGameInfo_Cmp CmpFun;
m_gameinfoList.sort(CmpFun);

 

 

2.修改list元素的值

list<NOTIFY_RECEIVE_HISTORY_GameInfo_PACKET>::iterator itGameInfo;

 

 for(itGameInfo = m_gameinfoList.begin(); itGameInfo != m_gameinfoList.end(); itGameInfo ++)
 { 
  if ( strcmp(itGameInfo->Gmcode ,GameInfoHistory.Gmcode) == 0  && strcmp(itGameInfo->round , GameInfoHistory.round ) ==0 )
  {
       NOTIFY_RECEIVE_HISTORY_GameInfo_PACKET *tmp=&(*itGameInfo);
       tmp->resbits = GameInfoHistory.resbits;
       strncpy(tmp->reslst,GameInfoHistory.reslst,sizeof(GameInfoHistory.reslst));
       break;
  }
 }
