Defines
#define	PCAP_BUF_SIZE   1024
	Defines the maximum buffer size in which address, port, interface names are kept.
#define	PCAP_SRC_FILE   2
	Internal representation of the type of source in use (file, remote/local interface).
#define	PCAP_SRC_IFLOCAL   3
	Internal representation of the type of source in use (file, remote/local interface).
#define	PCAP_SRC_IFREMOTE   4
	Internal representation of the type of source in use (file, remote/local interface).
#define	PCAP_SRC_FILE_STRING   "file://"
	String that will be used to determine the type of source in use (file, remote/local interface).
#define	PCAP_SRC_IF_STRING   "rpcap://"
	String that will be used to determine the type of source in use (file, remote/local interface).
#define	PCAP_OPENFLAG_PROMISCUOUS   1
	Defines if the adapter has to go in promiscuous mode.
#define	PCAP_OPENFLAG_DATATX_UDP   2
	Defines if the data trasfer (in case of a remote capture) has to be done with UDP protocol.
#define	PCAP_OPENFLAG_NOCAPTURE_RPCAP   4
	Defines if the remote probe will capture its own generated traffic.
#define	PCAP_OPENFLAG_NOCAPTURE_LOCAL   8
	Defines if the local adapter will capture its own generated traffic.
#define	PCAP_OPENFLAG_MAX_RESPONSIVENESS   16
	This flag configures the adapter for maximum responsiveness.
#define	PCAP_SAMP_NOSAMP   0
	No sampling has to be done on the current capture.
#define	PCAP_SAMP_1_EVERY_N   1
	It defines that only 1 out of N packets must be returned to the user.
#define	PCAP_SAMP_FIRST_AFTER_N_MS   2
	It defines that we have to return 1 packet every N milliseconds.
#define	RPCAP_RMTAUTH_NULL   0
	It defines the NULL authentication.
#define	RPCAP_RMTAUTH_PWD   1
	It defines the username/password authentication.
#define	RPCAP_HOSTLIST_SIZE   1024
	Maximum lenght of an host name (needed for the RPCAP active mode).

New WinPcap functions
This section lists the new functions that are able to help considerably in writing WinPcap programs because of their easiness of use.

Detailed Description

The goal of this file it to include most of the new definitions that should be placed into the pcap.h file.

It includes all new definitions (structures and functions like pcap_open(). Some of the functions are not really a remote feature, but, right now, they are placed here.

Definition in file remote-ext.h.
