SetConsoleCtrlHandler

linux下

signal(SIG_ID,/*处理函数*/);

void SignalSkill(int no)
{}
void ProcessSignal()
{
signal(SIGEXIT,SignalKill);
signal(SIGKILL,SignalKill);
signal(SIGPIPE,SIG_IGN); // send, recv 时网络断开,会收到SIGPIPE, 默认处理为进程终止, 所以忽略
signal(SIGHUP,SIG_IGN);//ssh终端退出,GameServer不退出
UlimitResource();
}

windows下

BOOL WINAPI SetConsoleCtrlHandler(

_In_opt_  PHANDLER_ROUTINE HandlerRoutine,

_In_      BOOL Add
