pfring_open(...)
pfring_recv(...)

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() that has not yet been activated by pcap_activate().
http://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 Eth-
ernet. For example, the "any" device on Linux will have a link-layer header type of DLT_LINUX_SLL even if all devices on the system 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 cre-
ated but not activated.
