file_pcap.h File Reference

Detailed Description

File I/O for packet capture files (PCAP, PCAPNG)

This file defines classes for reading and writing common packet-capture files as SatCat5 packet streams (i.e., io::Readable and io::Writeable).

Supported file formats include:

• PCAP v2.4
• PCAPNG

This implementation supports Ethernet packets only, using minimalist metadata where required. When writing files, packet timestamps are drawn from a provided datetime::Clock object.
