PCAP_DATALINK(3pcap)                                      PCAP_DATALINK(3pcap)

NAME
       pcap_datalink - get the link-layer header type

SYNOPSIS
       #include <pcap/pcap.h>

       int pcap_datalink(pcap_t *p);

DESCRIPTION
       pcap_datalink() returns the link-layer header type for the live capture
       or ``savefile'' specified by p.

       It   must   not   be   called   on   a   pcap   descriptor  created  by
       pcap_create(3PCAP)   that   has   not    yet    been    activated    by
       pcap_activate(3PCAP).

       https://www.tcpdump.org/linktypes.html lists the values pcap_datalink()
       can  return  and  describes the packet formats that correspond to those
       values.

       Do NOT assume that the packets for a given capture or ``savefile`` will
       have any given link-layer header type, such as DLT_EN10MB for Ethernet.
       For example, the "any" device on Linux will have  a  link-layer  header
       type of DLT_LINUX_SLL or DLT_LINUX_SLL2 even if all devices on the sys‐
       tem  at  the  time the "any" device is opened have some other data link
       type, such as DLT_EN10MB for Ethernet.

RETURN VALUE
       pcap_datalink() returns the  link-layer  header  type  on  success  and
       PCAP_ERROR_NOT_ACTIVATED  if  called  on a capture handle that has been
       created but not activated.
