Processing an UNREGISTER Request

An agent can send an UNREGISTER packet if some other subagent does a register for the same sub-tree at a higher priority. An agent can also send an UNREGISTER if, for example, an SNMP manager tells it to "invalidate" the subagent connection or the registered sub-tree.

Here is an example of how to handle such a packet.

#include <snmp_dpi.h>          /* DPI 2.0 API definitions */

static int do_unreg(snmp_dpi_hdr *hdr_p,
                    snmp_dpi_ureg_packet *pack_p)
{
  printf("DPI UNREGISTER received from agent, reason=%d\n",
          pack_p->reason_code);
  printf("    sub-tree=%s\n",pack_p->group_p);
  DPIdisconnect_from_agent(handle);
  return(-1); /* causes exit in main loop */
} /* end of do_unreg() */
