In Windows Visa/2008 guests and newer, it is possible to use inet_ntop()

and OnLinkPrefixLength to get IPv4 and IPv6 addresses and prefixes.
Why the double spacing?
Setting –extra-cflags in the build configuration to

”- D_WIN32_WINNT-0x600 -DWINVER=0x600” or greater enables this functionality
for those guests. Setting –ectra-cflags is not required and if not used,

Are you sure glib doesn't provide some sort of inet_ntop wrapper that
you could crib, instead of rolling your own? And if you must roll your
own, do it as a separate patch from the rest of this work, possibly by
copying from glibc or other existing implementation (with proper credits
to the upstream source), rather than writing it from scratch.
Agree. Moreover, there is separate functions for inet4 and inet6.
