As much as -possible going forward, the DLT_ and LINKTYPE_ value are identical, however, -this was not always the case. See pcap-common.c. - -The LINKTYPE_ values are not exported, but are in pcap-common.c only. - -DEVELOPER NOTES ---------------- - -When allocating a new DLT_ value, a corresponding value needs to be -added to pcap-common.c. -It is not necessary to copy the comments from dlt.h to pcap-common.c. |
