pcap_datalink_val_to_name, pcap_datalink_val_to_description - get a name or
description for a link-layer header type value
#include <pcap.h>
const char *pcap_datalink_val_to_name(int dlt);
const char *pcap_datalink_val_to_description(int dlt);
pcap_datalink_val_to_name() translates a link-layer header type value to
the corresponding link-layer header type name, which is the DLT_ name
for the link-layer header type value with the DLT_ removed. NULL
is returned if the type value does not correspond to a known DLT_
value.
pcap_datalink_val_to_description() translates a link-layer
header type value to a short description of that link-layer header type.
NULL is returned if the type value does not correspond to a known
DLT_ value.
