Синопсис (Synopsis)

Описание (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(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.

Возвращаемое значение (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.
