SYNOPSIS
#include <pcap/pcap.h>int pcap_can_set_rfmon(pcap_t *p);
DESCRIPTION
pcap_can_set_rfmon() checks whether monitor mode could be set on a capture handle when
the handle is activated.
RETURN VALUE
pcap_can_set_rfmon() returns 0 if monitor mode could not be set,
1 if monitor mode could be set,
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 check whether monitor mode
could be supported,
PCAP_ERROR_ACTIVATED if called on a capture handle that has been activated, or
