Defines
#define	PCAP_BUF_SIZE 1024
	Defines the maximum buffer size in which address, port, interface names are kept.

	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).
Functions
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.
pcap_t *	pcap_open (const char source, int snaplen, int flags, int read_timeout, struct pcap_rmtauth auth, char *errbuf)
int	pcap_createsrcstr (char source, int type, const char host, const char port, const char name, char *errbuf)
int	pcap_parsesrcstr (const char source, int type, char host, char port, char name, char errbuf)
int	pcap_findalldevs_ex (char source, struct pcap_rmtauth auth, pcap_if_t *alldevs, char errbuf)
pcap_samp *	pcap_setsampling (pcap_t *p)
Remote Capture functions
SOCKET	pcap_remoteact_accept (const char address, const char port, const char hostlist, char connectinghost, struct pcap_rmtauth auth, char errbuf)
int	pcap_remoteact_list (char hostlist, char sep, int size, char errbuf)
int	pcap_remoteact_close (const char host, char errbuf)
void	pcap_remoteact_cleanup ()

Detailed Description

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.
