pcap_set_promisc - set promiscuous mode for a not-yet-activated capture handle

  #include <pcap/pcap.h>
  int pcap_set_promisc(pcap_t *p, int promisc);

*pcap_set_promisc*() sets whether promiscuous mode should be set on a capture handle when the handle is activated. If promisc is non-zero, promiscuous mode will be set, otherwise it will not be set.

pcap_set_promisc*() returns *0 on success or PCAP_ERROR_ACTIVATED if called on a capture handle that has been activated.
