// PCAP is a standard file format for network capture files. This also extends
|
|
// to any capture of packetized intercommunication data. This file provides a
|
|
// class called PCAP which is a very light wrapper around the file format,
|
|
// allowing only creating a new PCAP capture file and appending packets to it.
|
|
//
|
|
// Example use:
|
|
// PCAP pcap(new IOFile("test.pcap", "wb"));
|
|
// pcap.AddPacket(pkt); // pkt is automatically casted to u8*
