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.

       The returned handle must be activated with pcap_activate() 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.  errbuf is assumed to be able to
       hold at least PCAP_ERRBUF_SIZE chars.
