"GNet is not developed any further. You should not use it in new software.
GNet should be considered deprecated and has been replaced by the newly-added platform-independent network and socket abstraction layer in GLib/Gio (with the release of GLib 2.22), ie. Lowlevel platform-independent network support, DNS resolution, and Highlevel network functionality.
The latest release is GNet 2.0.8 (February 12, 2008)"
