У меня есть программа, которая запускается как процесс зомби.Я хочу отладить это.Но я получил ошибку GDB.
mobile:/usr/local/ads5/bin# ps axf | grep ads_resolver

5584 pts/2 Zl 0:36 \_ [ads_resolver] <defunct>

Вот мой код, который создает процесс зомби:
template < class T>
int Monitor < T >::Start()
{
pid_t pid;
pid = fork();
if(pid == 0)
{
IgnoreSignal::IgnoreDaemon();
signal(SIGCHLD,Monitor<T>::ReStart);
pid = fork();
if(pid == 0)
{
IgnoreSignal::IgnoreAll();
T worker;
worker.Run();
}
while(1)
{
sleep(60);
}
}
return 0;
}
