Interface Alias creation using NetworkManager

[Girish Kumar Shetty <girishkumar shetty gmail com>]

Dear Experts,

      I am quite new-bie  for Network Manager  and looking for some information mentioned below, any help/pointers on these will be a great help.

•   I am just wondering, Is there a way to create an Alias for interface using Network Manager libraries( I mean, programmatically using libnm-glib and/or libnm-utils )?
•   And how can I configure IP4 information( like IP Addresses, Netmask, DNS, routes etc.,) to this alias interface. Could you please provide some hints on APIs?
•   Is it possible to get a notification If I run g_main_loop_run() as mentioned in libnm-glib-test.c when this alias is created and removed?  
•  I ran  executable created from 'libnm-glib-test.c'  and at the same time I have created an alias for eth0 manually by adding an entry eth0:0 n the /etc/network/interfaces ( and also tried using 'ifconfig' command in command line) in both cases 'ifconfig' command on terminal has shown the alias. But active_connection_changed call back function was not called. I was assuming that creation/deletion of on Alias will cause a change in active connection and 'active_connection_changed' callback function will be called.
  Could you please tell me what is the signal and callback function I have to register in-order to get the events on this alias interface creation an deletion.

    My OS : Ubuntu-12.10

    NetworkManager Version : 0.9.6

Thanks in Advance,
