Detailed Description

Simple libpcap interface definitions.

Creates a libpcap pcap_t listener for the given set of protocols. This is a much higher level, but much less flexible approach than the native libpcap interface.

WINEXPORT void close_pcap_listener	(	pcap_t *	,
		const char *	dev,
		unsigned	listenmask

Parameters

dev	device that this is opened on
listenmask	The 'listenmask' given to create_pcap_listener
