It seems that the "ioctl" function in Interactive UNIX doesn't
work correctly.
1. I tried to get the ifnet list by an ioctl call.
The parameter for "request" was "SIOCGIFCONF". Afterwards the
field "ifc_len" of the structure "ifconf" contained the value "0"
although there should have been some active interfaces.

2. I tried to get an ARP entry with "SIOCGARP". The structure
"arp_pa" within the structure "arpreq" contained as address
family "AF_INET" and an actual internet address. The ioctl call
didn't return. Even worse is that other ioctl calls which made
no problems before didn't return either afterwards.

I would be very glad about any helpful suggestions.
