The DPIsend_packet_to_agent() Function

Syntax

#include <snmp_dpi.h>

int DPIsend_packet_to_agent(       /* send  a DPI packet      */
  int                   handle,    /* on this connection      */
  unsigned char        *message_p, /* ptr to the packet data  */
  unsigned long         length);   /* length of the packet    */

Parameters

handle

A handle as obtained with a DPIconnect_to_agent_xxxx() call.
message_p
A pointer to the buffer containing the DPI packet to be sent.
length
The length of the DPI packet to be sent. The DPI_PACKET_LEN macro is a useful macro to calculate the length.

Return Values

If successful, a zero (DPI_RC_noError) is returned.

If failure, a negative integer is returned. It indicates the kind of error that occurred. See Return Codes from DPI Transport-Related Functions for a list of possible error codes.

Description

The DPIsend_packet_to_agent() function is used at the subagent side to send a DPI packet to the DPI capable SNMP agent.

Examples

  #include <snmp_dpi.h>  int                  handle;
  unsigned char       *pack_p;

  handle = DPIconnect_to_agent_TCP("localhost", "public");
  if (handle < 0) {
     printf("Error %d from connect\n",handle);
     exit(1);
  } /* endif */
  pack_p = mkDPIopen("1.3.6.1.2.3.4.5",
                "Sample DPI subagent"
                0L,2L,,DPI_NATIVE_CSET,
                0,(char *)0);
  if (pack_p) {
     rc = DPIsend_packet_to_agent(handle,pack_p,
                         DPI_PACKET_LEN(pack_p));
     if (rc) {
        printf("Error %d from await packet\n");
        exit(1);
     } /* endif */
  } else {
     printf("Can't make DPI OPEN packet\n");
     exit(1);
  } /* endif */
  /* await the response */
