GNet is a simple network library. It is written in C, object-oriented, and built upon GLib. It is intended to be small, fast, easy-to-use, and easy to port. The interface is similar to the interface for Java's network library.

GNet has been ported to Linux, BSD, macOS, Solaris, HP-UX, and Windows. It may work on other flavors of Unix too.

According to the GNet reference below,

GNet is very soon (with the release of GLib 2.22.0) going to be deprecated and replaced by the newly added platform-independent network and socket abstraction layer in GLib/Gio
