The DPI_PACKET_LEN() Macro

Syntax

#include <snmp_dpi.h>

int DPI_PACKET_LEN(unsigned char *packet_p)

Parameters

packet_p

A pointer to a serialized DPI packet.

Return Values

An integer representing the total DPI packet length.

Description

The DPI_PACKET_LEN macro generates C-code that returns an integer representing the length of a DPI packet. It uses the first two octets in network byte order of the packet to calculate the length.

Examples

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

  pack_p = mkDPIclose(SNMP_CLOSE_goingDown);
  if (pack_p) {
     length = DPI_PACKET_LEN(pack_p);
     /* send packet to agent or subagent */
  } /* endif */
