+ Returns a list of 2-tuples containing interface names and the

+ <c>Hwaddr</c> is hardware dependent, e.g on Ethernet interfaces
+ it is the 6-byte Ethernet address (MAC address (EUI-48 address)).
+ </p>
+ <p>
+ The <c>{addr,Addr}</c>, <c>{netmask,_}</c> and <c>{broadaddr,_}</c>
+ tuples are repeated in the result list iff the interface has multiple
+ addresses. If you come across an interface that has
+ multiple <c>{flag,_}</c> or <c>{hwaddr,_}</c> tuples you have
+ a really strange interface or possibly a bug in this function.
+ The <c>{flag,_}</c> tuple is mandatory, all other optional.

+ <c>Ifopt</c> tuples. There are some rules, though:
+ <list>
+ <item>
+ Immediately after <c>{addr,_}</c> follows <c>{netmask,_}</c>
+ </item>
+ <item>
+ Immediately thereafter follows <c>{broadaddr,_}</c> if

+ <c>pointtopoint</c>flag <em>is</em> set.
+ </item>
+ <item>
+ Any <c>{netmask,_}</c>, <c>{broadaddr,_}</c> or
+ <c>{dstaddr,_}</c> tuples that follow an <c>{addr,_}</c>
+ tuple concerns that address.
+ </item>
+ </list>
+ </p>
+ <p>
+ The <c>{hwaddr,_}</c> tuple is not returned on Solaris since the
+ hardware address historically belongs to the link layer and only
+ the superuser can read such addresses.
+ </p>
+ <p>
+ On Windows, the data is fetched from quite different OS API
+ functions, so the <c>Netmask</c> and <c>Broadaddr</c>
