By dissecting the raw packet data that WinPcap gives you; libpcap/WinPcap provide no APIs for dissecting raw packet data (because different libpcap/WinPcap applications have different needs - an intrusion detection application such as Snort and a packet analyzer such as tcpdump or Wireshark do different things with the data).

See, for example, libtins as a C++ library for doing packet dissection, or the libpcap tutorial for an example of how to do the dissecting yourself.
