14 | * This header defines the few things we need to write files in the pcap |
15 | * format. The identifiers are the same as in the system's pcap/pcap.h, but |
16 | * the types have been standardized. Note that the timestamp parts have to be |
17 | * put separately, since "struct timeval" may be padded. |
18 | * |
19 | * The reason for having our own header instead of just using pcap/pcap.h is |
20 | * to avoid a build-dependency on libpcap. |
