SNMP TRAP

今天写了一个关于snmp发trap命令的简单代码，仅供参考

  {
   return -1;
  }

  struct snmp_pdu *pdu;
  pdu = snmp_pdu_create(SNMP_MSG_TRAP2);

 if(!snmp_parse_oid(p_data->point_oid, id_oid, &id_len))
 {

  return -1;
 }

 printf("status = %d\n",status);
 status = snmp_send(ss,pdu);
 printf("status = %d\n",status);
 snmp_close(ss);
 return 0;
