how to do reconnection by subagent in code?

Hello!

I would like to change subagent settings in runtime, for example by HUP
signal.

Settings are MasterAgent address, port and subagent ping interval.

I tried:

int main()

{

...

init_agent("example-demon");

init_snmp("example-demon");

...

}

void OnHupSignal() /*just an example, not real code*/

{

/* CLOSE CONNECTION */

snmp_shutdown("example-demon");

/* CHANGE SETTINGS */

netsnmp_ds_set_string(NETSNMP_DS_APPLICATION_ID, NETSNMP_DS_AGENT_X_SOCKET,
address.c_str());

netsnmp_ds_set_int(NETSNMP_DS_APPLICATION_ID,
NETSNMP_DS_AGENT_AGENTX_PING_INTERVAL, interval);

/* INIT AGAIN */

init_agent("example-demon");

init_snmp("example-demon");

}

reconnection is done by init_snmp function(). But that function can be run
once only, see below:

void
init_snmp(const char *type)
{
  static int done_init = 0; /* To prevent double init's. */

  if (done_init) {
  return;
  }

  done_init = 1;
...

Is it possible to reconnect to MasterAgent in another way (without help of
exec(), fork() and etc.)? How to change settings correctly?

Thanks in advance.
