* This header defines the few things we need to write files in the pcap
|
|
* format. The identifiers are the same as in the system's pcap/pcap.h, but
|
|
* the types have been standardized. Note that the timestamp parts have to be
|
|
* put separately, since "struct timeval" may be padded.
|
|
*
|
|
* The reason for having our own header instead of just using pcap/pcap.h is
|
|
* to avoid a build-dependency on libpcap.
