20 .TH PCAP_CREATE 3PCAP "3 January 2014"
22 pcap_create \- create a live capture handle
26 #include <pcap/pcap.h>
31 char errbuf[PCAP_ERRBUF_SIZE];
35 pcap_t *pcap_create(const char *source, char *errbuf);
40 is used to create a packet capture handle to look
41 at packets on the network.
43 is a string that specifies the network device to open; on Linux systems
44 with 2.2 or later kernels, a
48 can be used to capture packets from all interfaces.
50 The returned handle must be activated with
52 before packets can be captured
53 with it; options for the capture, such as promiscuous mode, can be set
54 on the handle before activating it.
66 is filled in with an appropriate error message.
68 is assumed to be able to hold at least
72 pcap(3PCAP), pcap_activate(3PCAP)
