PCAP_DATALINK_VAL_TO_NAME(3PCAP)	      PCAP_DATALINK_VAL_TO_NAME(3PCAP)

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.

BACKWARD COMPATIBILITY
       The  pcap_datalink_val_to_description_or_dlt()  function	 first	became
       available  in   libpcap	 release   1.9.1.    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.
