24 pcap_create \- create a live capture handle
28 #include <pcap/pcap.h>
33 char errbuf[PCAP_ERRBUF_SIZE];
37 pcap_t *pcap_create(const char *source, char *errbuf);
42 is used to create a packet capture handle to look
43 at packets on the network.
45 is a string that specifies the network device to open; on Linux systems
46 with 2.2 or later kernels, a
50 can be used to capture packets from all interfaces.
52 The returned handle must be activated with
54 before packets can be captured
55 with it; options for the capture, such as promiscuous mode, can be set
56 on the handle before activating it.
68 is filled in with an appropriate error message.
70 is assumed to be able to hold at least
74 pcap(3PCAP), pcap_activate(3PCAP)
