c - Can't exitThread with waitForMultipleObjects -

-

i have 2 threads, first doing:`

while(1){      if(recv(conn_s, (char*) &i, sizeof(i),0)>0){          if(i==28){             setevent(event);             //printf("nell if di 28\n");             handle t;             sleep(1);             //terminatethread(scegli, 0);             //if (closehandle(scegli)==0) printf("error close\n");             t=createthread(null, 0, (lpthread_start_routine) avvia_conversazionecl, conn, synchronize, 0);             waitforsingleobject(t, infinite);

the second one: 

       const handle handles[2]={event, stdinhandle};         while(1){              switch(waitformultipleobjects(num, handles, false, 0)){                 case 0:                           exitthread(-1);                         break;                  case 1:                                     r=readconsole(stdinhandle, &interlocutore, nlength, &charsread, null);                                     if (r==0){                                         printf("%d\n", getlasterror());                                     }                                     //global_value_to_exit=1;                                     int size=strlen(interlocutore);                                      interlocutore[size-2]='\0';                                      int verifica=verifica_interlocutore(interlocutore);                                       if (verifica==0){                                          printf("interlocutore non disponibile, riprova: \n");                                          continue;                                     }                                        int rrr=send(socket, interlocutore, size, 0);                                     if (rrr<=0){                                         printf("send error\n");                                     }                                     sleep(1);                                     if(recv(socket, (char*) &ack, sizeof(int), 0)==socket_error){                                         printf("errore: %d\n", wsagetlasterror());                                     }                                     printf("ho ricevuto %d\n", (int) ack);                                     if(ack==999){                                          //sleep(1);                                          handle t;                                         dword tid;                                         t=createthread(null, 0, (lpthread_start_routine) avvia_conversazionecl, conn_s, 0, &tid);                                         waitforsingleobject(t, infinite);                                         closehandle(t);                                         //global_value_to_exit=0;                                         ack=0;                                         vis=createthread(null, 0, (lpthread_start_routine) visualizza_utenti, conn_s, 0, &visid);                                      }                                      //resetevent(stdinhandle);                                      break;                  case wait_failed:                                  perror("failed: \n");                                  break;     }      memset(interlocutore, 0, sizeof(interlocutore)); }      return null;  }

also: 

  const handle handles[2]={event, stdinhandle};     event=createevent(null, false, false, null);     stdinhandle=getstdhandle(std_input_handle);`

the point is: if write in console things second thread, if 28 receive make second thread exit sett signaled event. @ point waitformultipleobjects should case 0 , exit thread. instead after i've recv 28 , changed status of event, if write in console second thread enters case 1. after writing else seems dead

any advice?

ios - Memory not freeing up after popping viewcontroller using ARC -

hi project arc based, using uinavigationcontroller make transition between viewcontroller. using profiler analyse happening behind scene memory. noticed when push viewcontroller allocate memory components , when pop not freeing allocated memory. since using arc unable implement dealloc or release component. have analysed in detail , there no memory leak in project. i not using strong property push viewcontroller. here how pushing viewcontroller. viewcontroller *obj = [[viewcontroller alloc] init]; [self.navigationcontroller pushviewcontroller:obj animated:no]; any clue whats going on? should free memory have consumed. please advise your description indicates have retain cycle, leads objects not being deallocated. typical source of retain cycles properties assigned loading nib files (usually declared iboutlet ). two strategies break them , release objects: declare property weak : @property (nonatomic, weak) iboutlet uilabel *statuslabel; set property nil in...
