Empty string wasn't good enough? Why not just memset(ssid, 0, 32) ? IMO, since the output here is meant to be parsed by other programs, this needs to change. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

/usr/sbin/iwconfig is part of wireless-tools. Vladimir, is this yours?
Yes. It is. I understand the problem but iwconfig is going to be replaced with iw [1,2] . NM shall be working with this. In the scripts it would be good to use iw for future compatibility. Jon, if there are no serious objections can I close it here as WONTFIX ?

If the answer is 'no' then go ahead and close. Otherwise, it seems to me that the bug would *also* apply to 'iw'. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
