What's a ".dmp" file?
If that's the file format that Ethereal/Wireshark reads and writes by
default (for which there's no "official" standard suffix - it originated
on UN*X, in the command-line tcpdump program, so there wasn't a standard
suffix assigned to it), then the best way to describe the format is "the
format supported by the libpcap/WinPcap library".
The best way to read it is not to write your own code to understand the
format, the best way to read it is to use libpcap/WinPcap to read it; it
means you write less code (you don't have to write code to understand
the file format), and the code you do write will continue to work with
pcap-ng files when that's supported by libpcap/WinPcap and Wireshark.
If you're using UN*X, try "man pcap" or see
http://www.tcpdump.org/pcap3_man.html
If you're using Windows, see
http://www.winpcap.org/docs/docs31/html/main.html
