# dump_bpf_hdr Struct Reference
[Packet.dll definitions and data structures]

Dump packet header. More...

`#include <Packet32.h>`

## Data Fields
timeval | ts
| Time stamp of the packet.
UINT | caplen
UINT | len
| Length of the original packet (off wire).

## Detailed Description

Dump packet header.

This structure defines the header associated with the packets in a buffer to be used with PacketSendPackets(). It is simpler than the bpf_hdr, because it corresponds to the header associated by WinPcap and libpcap to a packet in a dump file. This makes straightforward sending WinPcap dump files to the network.

## Field Documentation

UINT caplen

| Length of captured portion. The captured portion can smaller than the the original packet, because it is possible (with a proper filter) to instruct the driver to capture only a portion of the packets. Definition at line 175 of file Packet32.h.

UINT len

| Length of the original packet (off wire). Definition at line 178 of file Packet32.h.

struct timeval ts

| Time stamp of the packet. Definition at line 174 of file Packet32.h.
