PCAP_SET_PROTOCOL_LINUX(3pcap)PCAP_SET_PROTOCOL_LINUX(3pcap)
NAME
pcap_set_protocol_linux - set capture protocol for a not-yet-activated
capture handle
SYNOPSIS
#include <pcap/pcap.h>
int pcap_set_protocol_linux(pcap_t *p, int protocol);
DESCRIPTION
On network interface devices on Linux, pcap_set_protocol_linux() sets
the protocol to be used in the socket(2) call to create a capture
socket when the handle is activated. The argument is a link-layer pro‐
tocol value, such as the values in the <linux/if_ether.h> header file,
specified in host byte order. If protocol is non-zero, packets of that
protocol will be captured when the handle is activated, otherwise, all
packets will be captured. This function is only provided on Linux,
and, if it is used on any device other than a network interface, it
will have no effect.
It should not be used in portable code; instead, a filter should be
specified with pcap_setfilter(3PCAP).
If a given network interface provides a standard link-layer header,
with a standard packet type, but provides some packet types with a dif‐
ferent socket-layer protocol type from the one in the link-layer
header, that packet type cannot be filtered with a filter specified
with pcap_setfilter() but can be filtered by specifying the socket-
layer protocol type using pcap_set_protocol_linux().
RETURN VALUE
pcap_set_protocol_linux() returns 0 on success or PCAP_ERROR_ACTIVATED
if called on a capture handle that has been activated.
BACKWARD COMPATIBILITY
This function became available in libpcap release 1.9.0.
