Detailed Description

A class for opening a pcap file in read-only mode. This class enable to open the file and read all packets, packet-by-packet

Constructor & Destructor Documentation

PcapFileReaderDevice()

pcpp::PcapFileReaderDevice::PcapFileReaderDevice ( const char *  fileName )

inline

A constructor for this class that gets the pcap full path file name to open. Notice that after calling this constructor the file isn't opened yet, so reading packets will fail. For opening the file call open()

Parameters

[in]

fileName

The full path of the file to read

~PcapFileReaderDevice()

virtual pcpp::PcapFileReaderDevice::~PcapFileReaderDevice ( )

inlinevirtual

A destructor for this class

Member Function Documentation

getLinkLayerType()

LinkLayerType pcpp::PcapFileReaderDevice::getLinkLayerType ( ) const

inline

Returns

The link layer type of this file

getNextPacket()

bool pcpp::PcapFileReaderDevice::getNextPacket ( RawPacket &  rawPacket )

virtual

Read the next packet from the file. Before using this method please verify the file is opened using open()

Parameters

[out]

rawPacket

A reference for an empty RawPacket where the packet will be written

Returns

True if a packet was read successfully. False will be returned if the file isn't opened (also, an error log will be printed) or if reached end-of-file

Implements pcpp::IFileReaderDevice.

getStatistics()

void pcpp::PcapFileReaderDevice::getStatistics ( pcap_stat &  stats ) const

virtual

Get statistics of packets read so far. In the pcap_stat struct, only ps_recv member is relevant. The rest of the members will contain 0

Parameters

[out]

stats

The stats struct where stats are returned

Implements pcpp::IPcapDevice.

open()

bool pcpp::PcapFileReaderDevice::open ( )

virtual

Open the file name which path was specified in the constructor in a read-only mode

Returns

True if file was opened successfully or if file is already opened. False if opening the file failed for some reason (for example: file path does not exist)

Implements pcpp::IDevice.
