Re: [osip-dev] Execution gets stuck at eXosip_event_wait

[Aymeric Moizard]

Hi Firman,

First, you must not "break" after the "EXOSIP_REGISTRATION_FAILURE". This will happen

usually before it succeed and is "normal operation" process. If you break, you will not

receive the next EXOSIP_REGISTRATION_SUCCESS event.

    }else if(evt->type == EXOSIP_REGISTRATION_FAILURE){

      fprintf(stderr, "Failure\n");

      //break;

Otherwise, I don't see any error in your code and according to me,

it should only wait in that method 50ms.

May be you can provide the backtrace and logs.

Hi Aymeric,

I followed your advice to run eXosip_event_wait in a loop but it seems that the execution stops right at that line of the code which calls eXosip_event_wait. Any advise as to what causes it? Thanks in advace.

#include <sys/socket.h>

#include <netinet/in.h>

#include <eXosip2/eXosip.h>

int registerClient(eXosip_t*);

int main(){

  // Initialize the osip trace (compile this code with -DENABLE_TRACE)

  eXosip_t *ctx;

  int i;

  int port = 5060;

  //TRACE_INITIALIZE(6, NULL);

  // Initialize eXosip (and osip) stack

  ctx = eXosip_malloc();

  if(ctx == NULL){

    return -1;

  }

  i = eXosip_init(ctx);

  if(i != 0){

    return -1;

  }

  eXosip_set_user_agent(ctx, "Firman");

  // Open a UDP socket for signalling

  i = eXosip_listen_addr(ctx, IPPROTO_UDP, NULL, port, AF_INET, 0);

  if(i!=0){

    eXosip_quit(ctx);

    fprintf (stderr, "could not initialize transport layer\n");

    return -1;

  }

  registerClient(ctx);

}

int registerClient(eXosip_t *ctx){

  fprintf(stdout, "Register client\n");

  // Initialize a registration

  osip_message_t *reg = NULL;

  int rid;

  int i;

  eXosip_lock(ctx);

  rid = eXosip_register_build_initial_register(ctx, "sip:address@hidden", "sip.antisip.com", NULL, 1800, &reg);

  osip_message_set_supported(reg, "100rel");

  osip_message_set_supported(reg, "path");

  i = eXosip_register_send_register(ctx, rid, reg);

  eXosip_unlock(ctx);

  eXosip_event_t *evt;

  while(true){

    fprintf(stderr, "Start\n");

    fprintf(stderr, "%d\n", rid);

    

    evt = eXosip_event_wait(ctx, 0, 50);

    eXosip_lock(ctx);

    eXosip_automatic_action(ctx);

    eXosip_unlock(ctx);

    

    fprintf(stderr, "Check event\n");

    if(evt == NULL){

      fprintf(stderr, "NULL\n");

      continue;

    }

    if(evt->type == EXOSIP_REGISTRATION_SUCCESS){

      fprintf(stderr, "Success\n");

      break;

    }else if(evt->type == EXOSIP_REGISTRATION_FAILURE){

      fprintf(stderr, "Failure\n");

      break;

    }

    fprintf(stderr, "%d\n", evt->type);

  }

  fprintf(stderr, "Out of the loop");

  return i;

}
