		uint32_t	snapLen = `std::numeric_limits<uint32_t>::max ()`,
		int32_t	tzCorrection = `PcapFile::ZONE_DEFAULT`
	)

Initialize the pcap file associated with this wrapper.

This file must have been previously opened with write permissions.

Parameters

dataLinkType	A data link type as defined in the pcap library. If you want to make resulting pcap files visible in existing tools, the data link type must match existing definitions, such as PCAP_ETHERNET, PCAP_PPP, PCAP_80211, etc. If you are storing different kinds of packet data, such as naked TCP headers, you are at liberty to locally define your own data link types. According to the pcap-linktype man page, "well-known" pcap linktypes range from 0 to 177. If you use a large random number for your type, chances are small for a collision.
snapLen	An optional maximum size for packets written to the file. Defaults to 65535. If packets exceed this length they are truncated.
tzCorrection	An integer describing the offset of your local time zone from UTC/GMT. For example, Pacific Standard Time in the US is GMT-8, so one would enter -8 for that correction. Defaults to 0 (UTC).

Warning: Calling this method on an existing file will result in the loss any existing data.

Here is the call graph for this function:

void ns3::PcapFileWrapper::Open	(	std::string const &	filename,
		std::ios::openmode	mode
	)

Create a new pcap file or open an existing pcap file.

Semantics are similar to the stdc++ io stream classes.

Since a pcap file is always a binary file, the file type is automatically selected as a binary file (fstream::binary is automatically ored with the mode field).

Parameters

filename	String containing the name of the file.
mode	String containing the access mode for the file.

Here is the call graph for this function:

void ns3::PcapFileWrapper::Write	(	Time	t,
		Ptr< const Packet >	p
	)

Write the next packet to file.

Parameters

t	Packet timestamp as ns3::Time.
p	Packet to write to the pcap file.

Here is the call graph for this function:

Here is the caller graph for this function:

void ns3::PcapFileWrapper::Write	(	Time	t,
		Header &	header,
		Ptr< const Packet >	p
	)

Write the provided header along with the packet to the pcap file.

It is the case that adding a header to a packet prior to writing it to a file must trigger a deep copy in the Packet. By providing the header separately, we can avoid that copy.

Parameters
