### Here is a function called create_gNB_tasks with such code

int create_gNB_tasks(uint32_t gnb_nb) {
  LOG_D(GNB_APP, "%s(gnb_nb:%d)\n", __FUNCTION__, gnb_nb);
  itti_wait_ready(1);

  if (gnb_nb > 0) {

    if(itti_create_task(TASK_SCTP, sctp_eNB_task, NULL) < 0) {
      LOG_E(SCTP, "Create task for SCTP failed\n");
      return -1;
    }

    if (is_x2ap_enabled()) {
      if(itti_create_task(TASK_X2AP, x2ap_task, NULL) < 0) {
        LOG_E(X2AP, "Create task for X2AP failed\n");
      }
    } else {
      LOG_I(X2AP, "X2AP is disabled.\n");
    }
  }
