PCAP_LOOKUPDEV(3pcap)                                    PCAP_LOOKUPDEV(3pcap)



NAME
       pcap_lookupdev - find the default device on which to capture

SYNOPSIS
       #include <pcap/pcap.h>

       char errbuf[PCAP_ERRBUF_SIZE];

       [DEPRECATED] char *pcap_lookupdev(char *errbuf);

DESCRIPTION
       This  interface  is  obsoleted  by  pcap_findalldevs(3PCAP).  To find a
       default device on which to capture, call pcap_findalldevs() and, if the
       list  it  returns  is not empty, use the first device in the list.  (If
       the list is empty, there are no devices on which capture is possible.)

       pcap_lookupdev() returns a pointer to a string giving  the  name  of  a
       network   device   suitable   for   use   with  pcap_create(3PCAP)  and
       pcap_activate(3PCAP),   or   with   pcap_open_live(3PCAP),   and   with
       pcap_lookupnet(3PCAP).   If  there  is  an  error, NULL is returned and
       errbuf is filled in with  an  appropriate  error  message.   errbuf  is
       assumed to be able to hold at least PCAP_ERRBUF_SIZE chars.

BUGS
       The pointer returned by pcap_lookupdev() points  to  a  static  buffer;
       subsequent  calls  to  pcap_lookupdev() in the same thread, or calls to
       pcap_lookupdev() in another thread, may overwrite that buffer.

       In WinPcap, this function may return a UTF-16  string  rather  than  an
       ASCII or UTF-8 string.
