wi: scanning for network names

Hi

I've written some code that ioctl's WI_RID_SCAN_REQ and then gets the 
responses after a short sleep with WI_RID_SCAN_RES

code available http://moat.nlanr.net/~mjl/wiscan.c

This is on a FreeBSD 4.6 laptop with sources cvsup'd 4 hours ago, and

wi0 at port 0x240-0x27f irq 10 slot 0 on pccard0
wi0: 802.11 address: 00:02:2d:03:0c:0c
wi0: using Lucent Technologies, WaveLAN/IEEE
wi0: Lucent Firmware: Station 8.10.01

How should I interpret wreq.wi_len?

26 (see output below) isn't enough for sizeof(struct wi_scan_res) and it 
certainly isn't the number of wireless network names it found.

sizeof wi_data 1024
scanbuf_len 26
sizeof wi_scan_res 62
