/* Linux Prism II Stumbler - Utility Scan for 802_11 networks under Linux
 * 
 * File : functions.h
 * Project : WifiScanner (c) 2002 Hervé Schauer Consultants
 * Usage : This utility is written for use with IEEE 802.11 adapters based
 * on Intersil's PRISM II chipset (PCMCIA).
 * 
 * Base code was from prismstumbler Jan Fernquist <Jan.B.Fernquist@telia.com>
 * and wlanctl from www.linux-wlan.com
