       const char *pcap_datalink_val_to_name(int dlt);

Описание (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.

Обратная совместимость (Backward compatibility)

The pcap_datalink_val_to_description_or_dlt() function first
       became available in libpcap release 1.10.0.  In previous
       releases, pcap_datalink_val_to_description() would have to be
       called and, if it returned NULL, a default string would have to
       be constructed.
