       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
