What is a PCAP file?
Developed by Wireshark, a network protocol analyzer program, the PCAP (Packet Capture) extension is the standard format for data sniffing from network packets. The form is useful in analyzing the network characteristics of a given data file. The sniffing is possible via software using the WinPcap, Ncpap, or Libpcap libraries.
The PCAP API is C-based, which means other programming languages will require a wrapper to access such files. Even C++ occasionally needs it to connect to the C API.
