This is in excerpt of my code at the beginning (in C):

  /* print log errors to syslog or stderr */
  if (background)
    snmp_enable_calllog();
  else
    snmp_enable_stderrlog();

  /* we're an agentx subagent? */
  if (agentx_subagent) {
    /* make us a agentx client. */
    netsnmp_ds_set_boolean(NETSNMP_DS_APPLICATION_ID, NETSNMP_DS_AGENT_ROLE, 1);
  }

  /* run in background, if requested */
  if (background && netsnmp_daemonize(1, !slog))
    exit(1);

  /* initialize tcpip, if necessary */
  SOCK_STARTUP;

      /*set IP and port of MasterAgent*/
      sprintf_s(connectionInfoAgentX,SMALL_BUFFER,"tcp:%s:%s",SnmpMasterAgentIp,SnmpPort);
      info=netsnmp_ds_set_string(NETSNMP_DS_APPLICATION_ID,NETSNMP_DS_AGENT_X_SOCKET, connectionInfoAgentX);
      Log(3,"Return of netsnmp_ds_set_string(): %d",info);



  /* initialize the agent library */
  info=init_agent("omgagent");
  Log(3,"Return of init_agent(): %d",info);



  /* initialize our mib */
      /* 1st init tables */
      init_mib_physicalInterfacesTable();
      init_mib_bChannelTable();
      init_mib_sessionTable();


  // Preset with environment value
  getenvError=getenv_s(&getenvRetValue,envval,SMALL_BUFFER,"SNMPLOCATION");
  if (strlen(envval)!=0) {
    scalar_setstr(&mib_scalar_Location, envval);
  }
  else {
    scalar_setstr(&mib_scalar_Location, "Lost in space");
  }
  getenvError=getenv_s(&getenvRetValue,envval,SMALL_BUFFER,"sn");
  if (strlen(envval)!=0) {
    scalar_setstr(&mib_scalar_Productname, envval);
  }
  else {
    scalar_setstr(&mib_scalar_Productname, "99999");
  }
  getenvError=getenv_s(&getenvRetValue,envval,SMALL_BUFFER,"VUSER");
  if (strlen(envval)!=0) {
    scalar_setstr(&mib_scalar_SoftwareVersion, envval);
  }
  else {
    scalar_setstr(&mib_scalar_SoftwareVersion, "");
  }
  getenvError=getenv_s(&getenvRetValue,envval,SMALL_BUFFER,"VUTILS");
  if (strlen(envval)!=0) {
    scalar_setstr(&mib_scalar_UtilityVersion, envval);
  }
  else {
    scalar_setstr(&mib_scalar_UtilityVersion, "");
  }
  getenvError=getenv_s(&getenvRetValue,envval,SMALL_BUFFER,"VMODULES");
  if (strlen(envval)!=0) {
    scalar_setstr(&mib_scalar_ModuleVersion, envval);
  }
  else {
    scalar_setstr(&mib_scalar_ModuleVersion, "");
  }

  scalar_setstr(&mib_scalar_TrapMessage,"");
  scalar_setstr(&mib_scalar_fmsrvComponentsUndev, "");

  init_mib_scalar();


  init_snmp("omgagent");  //say hello to snmpd


  /* In case we receive a request to stop (kill -TERM or kill -INT) */
  keep_running = 1;
  signal(SIGTERM, stop_server);
  signal(SIGINT, stop_server);


  snmp_log(LOG_INFO,"omgagent is up and running.\n");
  Log(3,"Connect to SNMP Master AgentX (IP:%s Port:%s)",SnmpMasterAgentIp,SnmpPort);

---------------------
The function "scalar_setstr()":
void scalar_setstr(char **scalar, char *string)
{
    if (*scalar)
    {
    free(*scalar);
    }

    *scalar = malloc(strlen(string)+1);
    strcpy(*scalar, string);
}

>(You'd use 'usleep' for finer-grained delays)

I'm writing in C, there is the definition of Sleep() like that:

VOID WINAPI Sleep(
  __in  DWORD dwMilliseconds
);
The time interval for which execution is to be suspended, in milliseconds.

Thanks for your rapid help!!
