Try it. If that doesn't work, debug the process. If that still doesn't work, google any error messages. If that still doesn't work, come back here and explain what happened.
The above process helps you to learn. People on forums are much more willing to help you after you've tried to help yourself first.
PS: this isn't any type of flame or slam - I'm just explaining the process

pcap_activate
PCAP_ACTIVATE(3PCAP) PCAP_ACTIVATE(3PCAP)
NAME
pcap_activate - activate a capture handle
SYNOPSIS
#include <pcap/pcap.h>
int pcap_activate(pcap_t *p);
DESCRIPTION
pcap_activate() is used to activate a packet capture handle to look at packets on the network, with the options that were set on the handle
being in effect.
RETURN VALUE
pcap_activate() returns 0 on success without warnings, PCAP_WARNING_PROMISC_NOTSUP on success on a device that doesn't support promiscuous
mode if promiscuous mode was requested, PCAP_WARNING_TSTAMP_TYPE_NOTSUP on success if the time stamp type specified in a previous
pcap_set_tstamp_type() call isn't supported by the capture source (the time stamp type is left as the default), PCAP_WARNING on success
with any other warning, PCAP_ERROR_ACTIVATED if the handle has already been activated, PCAP_ERROR_NO_SUCH_DEVICE if the capture source
specified when the handle was created doesn't exist, PCAP_ERROR_PERM_DENIED if the process doesn't have permission to open the capture
source, PCAP_ERROR_PROMISC_PERM_DENIED if the process has permission to open the capture source but doesn't have permission to put it into
promiscuous mode, PCAP_ERROR_RFMON_NOTSUP if monitor mode was specified but the capture source doesn't support monitor mode,
PCAP_ERROR_IFACE_NOT_UP if the capture source is not up, and PCAP_ERROR if another error occurred. If PCAP_WARNING or PCAP_ERROR is
returned, pcap_geterr() or pcap_perror() may be called with p as an argument to fetch or display a message describing the warning or error.
If PCAP_WARNING_PROMISC_NOTSUP, PCAP_ERROR_NO_SUCH_DEVICE, or PCAP_ERROR_PERM_DENIED is returned, pcap_geterr() or pcap_perror() may be
called with p as an argument to fetch or display an message giving additional details about the problem that might be useful for debugging
the problem if it's unexpected.
