PCAP_DATALINK_VAL_TO_NAME(3)                  FreeBSD Library Functions Manual

NAME
       pcap_datalink_val_to_name, pcap_datalink_val_to_description,
       pcap_datalink_val_to_description_or_dlt - get a name or description for
       a link-layer header type value

SYNOPSIS
       #include <pcap.h>

       const char *pcap_datalink_val_to_name(int dlt);
       const char *pcap_datalink_val_to_description(int dlt);
       const char *pcap_datalink_val_to_description_or_dlt(int dlt);

DESCRIPTION
       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.

       pcap_datalink_val_to_description_or_dlt() translates a link-layer
       header type value to a short description of that link-layer header type
       just like pcap_datalink_val_to_description.  If the type value does not
       correspond to a known DLT_ value, the string "DLT n" is returned, where
       n is the value of the dlt argument.
