создать дескриптор записи в реальном времени (create a live capture handle)
Имя (Name)
pcap_create - create a live capture handle
Синопсис (Synopsis)
#include <pcap/pcap.h>
char errbuf[PCAP_ERRBUF_SIZE];
pcap_t *pcap_create(const char *source, char *errbuf);
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.
