If you use the correct set of ioctl()'s it will, just as
"/sbin/ifconfig -a" lists all interfaces regardless of whether they
have IP addresses.

Run strace on 'ifconfig', see what it does :-)

And then you also have the option of using netlink as well.
This is how "ip l l" lists all interfaces, also regardless of
configuration.
