Hi, For the last days I have been struggling to reap zombies adopted by the frontend with only failures. I tried several methods using wait(-1), waidpid and trapping the signal when a child dies without ever succeeding to reap zombies. This means, I will stop and will leave the issue open to anyone who can find a working solution. With zombies or not, the application works. So I will continue with real development instead of fighting a seeming impossible battle.
The pascal code that I used to reap zombies: ====================================== procedure handle_sigchld(sig: longint; info: psiginfo; context: psigcontext); cdecl; var Status: cint; a_pid: pid_t; begin Status := 0; a_pid := -1; { SIGCHLD CLD_EXITED child has exited CLD_KILLED child was killed CLD_DUMPED child terminated abnormally CLD_TRAPPED traced child has trapped CLD_STOPPED child has stopped CLD_CONTINUED stopped child had continued } //CLD_EXITED = 1; CLD_KILLED = 2 if info^.si_code = 2 then begin backend_lives := backend_lives + 1; //fpwaitpid(a_pid, Status, WNOHANG); //fpwaitpid(info^._sifields._sigchld._pid, info^._sifields._sigchld._status, WNOHANG); //fpwait(info^._sifields._sigchld._pid); //, info^._sifields._sigchld._status, WNOHANG); //info^._sifields._sigchld._pid:=; //while fpwait(a_pid) > 0 do; s := s + inttostr(info^.si_code) + '.'; { while (fpwaitpid(a_pid, Status, WNOHANG) > 0) do begin backend_lives := backend_lives + 1; end; } end; end; var sa: sigactionrec; initialization sa.sa_handler := @handle_sigchld; fpsigemptyset(&sa.sa_mask); sa.sa_flags := (SA_RESTART or SA_NOCLDSTOP); if (fpsigaction(SIGCHLD, @sa, nil) = -1) then begin // do nothing end; ====================================== Edward On 03/09/2015, poitr pogo <lepo...@gmail.com> wrote: > hmm, I do wifi connect in bash/xterm > > one shot > sudo vi /etc/network/interfaces > add > > source /etc/network/interfaces.d/*.cfg > > if not already there > > make sure /etc/network/interfaces.d folder exists > > later, check what is available > > sudo iwlist wlan0 scanning |grep -e ESSID -e Quality > Quality=70/70 Signal level=-40 dBm > ESSID:"apn 1" > > If never used one before > > sudo /etc/network/interfaces.d/apn_1.cfg > > iface apn_1 inet dhcp > wpa-ssid "apn 1" > wpa-psk mypass1234 > > > from now on to connect to "apn 1" I just do > > sudo ifup wlan0=apn_1 > > > -- > > regards > piotr > _______________________________________________ > Dng mailing list > Dng@lists.dyne.org > https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng > _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
