error: '

'_localtime_not_threadsafe_' was not declared in this scope

 

多线程安全问题，不能直接用localtime，而要用localtime_r函数

 

1080     time_t timer;

1081     time(&timer);

1082 

1083     struct tm *t_tm;

1084     char tmpbuf[8];

1085     //t_tm = localtime_r(&timer,t_tm);

1086     localtime_r(&timer,t_tm);

1087     //strftime(tmpbuf,128,"%F %X", newtime);

1088     sprintf(tmpbuf,"Mdd", t_tm->tm_year, t_tm->tm_mon, t_tm->tm_mday);
