NAME
       pcap_create - create a live capture handle


SYNOPSIS
       #include <pcap/pcap.h>

       char errbuf[PCAP_ERRBUF_SIZE];

       pcap_t *pcap_create(const char *source, char *errbuf);


DESCRIPTION
       pcap_create()  is  used to create a packet capture handle to look at packets on the network.  source is a
       string that specifies the network device to open; on Linux systems with 2.2 or later  kernels,  a  source
       argument  of  "any" or NULL can be used to capture packets from all interfaces.  errbuf is a buffer large
       enough to hold at least PCAP_ERRBUF_SIZE chars.

       The returned handle must be activated with pcap_activate(3PCAP) before packets can be captured  with  it;
       options for the capture, such as promiscuous mode, can be set on the handle before activating it.


RETURN VALUE
       pcap_create()  returns  a pcap_t * on success and NULL on failure.  If NULL is returned, errbuf is filled
       in with an appropriate error message.
