I need to enumerate local network interfaces (IPv4, IPv6), getting their addresses and netmasks. The code which should run both under Linux and newly under Windows (mingw64).
I was looking at getaddrinfo which is somewhat cross-platform (both POSIX and in ws2tcpip.h) but could not obtain the netmask part.
The Linux part currently uses getifaddrs. I am deciding whether to use native APIs (getifaddrs in Linux, GetInterfaceInfo in Windows) or a cross-platform layer.
The code already uses glib/gio heavily: does it have cross-platform layer for network interface enumeration?
