ioctl and stuff

[Zomba]

I make a 
s=socket(AF_INET, SOCK_DGRAM)
res= fcntl.ioctl(s.fileno(), 0xc020690d, 'le1' + '\0' *29)

the 0xc020690d call, work pretty well, i can take from res (with struct.unpack) the ip addr of my device, but the problem is:

fcntl.ioctl(s.fileno(), 0xc020690c, res)
and it said: "Errno 22 - Invalid Argument" 
 
(I try this, because i make my own 'res' with other information, but it had the same error)

Im working on OpenBSD, the 0xc020690d is OSIOCGIFADDR and 0xc020690c is SIOCSIFADDR

Ideas??!

Thanks in advance ppls
