[Madwifi-devel] Trouble with MLME ioctl call?

[Joshua C. <jp...@ki...>]

I'm trying to implement some associate/disassociate code based on the  
boilerplate code here:

http://madwifi.org/wiki/ChipsetFeatures/Roaming

When I run the code, I get an error message stating that the private  
ioctl call for ath0 failed. I noticed there is a comment right above  
the code on the website which says: "currently there are errors in  
these functions, somehow they do not work", so I'm not terribly  
surprised.

I do need a workaround though. Can anyone tell me either:

1) If it is obvious to someone with more experience, why these  
functions don't work?
2) If it isn't obvious, how do I debug them? Is there a way to get  
the reason the ioctl called, rather than just 'error'?
3) Is there a work around for a user-space program? I've written a  
script which brings down the interface (ifconfig down, etc) and  
brings it back up on a specific AP, but I would rather avoid making  
an exec() call from my code if possible. Also, this seems slower than  
triggering a re-association with the interface up.
