Creating virtual interface using C++

Dear All,

Can someone give me suggestion for C++ codes that will create a
virtual network interface for the existing network interface
(including wired and wireless network interface)?

Regards,

It depends what you mean by virtual. Normally, you should use /dev/net/tun 
which is documented at linux-2.6/Documentation/networking/tuntap.txt

for the existing network interface
(including wired and wireless network interface)?

But that part of your question does not make any sense.

Don't know how to explain by virtual. But, you know the "iw" utility
(http://wireless.kernel.org/en/users/Documentation/iw)? If you
installed this utility, and then run the command "sudo iw dev
<wireless interface> interface add <virtual interface name> type
<wireless mode>", for example "sudo iw dev wlan0 interface add mon0
type monitor", it will add an virtual wireless interface named "mon0"
for the wireless interface "wlan0", then switch it to monitor mode. if
you run that command, you will know what I mean.
