(usagi-users 02869) getifaddrs();

[Willim Sanchez <wsanchez@xxxxxxxxxxxxxx>]

While running the getifaddrs-test.c program from USAGI, I see that the 
link local address has a "%253" at the end of the address while the site 
local address does not have that, can some one tell me what does it 
mean. The output looks as  follows:

Interface: lo
       Address: [127.0.0.1]
       Netmask: [255.0.0.0]
       Bcast: [127.0.0.1]


Interface: lo
       Address: [::1]
       Netmask: [ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff]
       Bcast:
------
Interface: eth0
       Address: [fec0::1:204:76ff:fe39:6388]
       Netmask: [ffff:ffff:ffff:ffff::]
       Bcast:
------
Interface: eth0
       Address: [fe80::204:76ff:fe39:6388%253]
       Netmask: [ffff:ffff:ffff:ffff::]
       Bcast:
------
Runing ifconfig I have the following.
