char errbuf[PCAP_ERRBUF_SIZE];
[DEPRECATED] char *pcap_lookupdev(char *errbuf);
pcap_lookupdev() returns a pointer to a string giving the name of a network device suitable for use with pcap_create() and pcap_activate(), or with pcap_open_live(), and with pcap_lookupnet(). 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.
In WinPcap, this function may return a UTF-16 string rather than an ASCII or UTF-8 string.
