NAME         top

       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         top

       #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         top

       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.
