GLib is a general-purpose and cross-platform utility library, which provides many useful data types, macros, type conversions, string utilities, file utilities, a main loop abstraction, and so on.

For many applications, C with GLib and GObject is an alternative to C++ with STL. It works on many UNIX-like platforms, Windows, OS/2 and BeOS. GLib is released under the GNU Library General Public License (GNU LGPL).

The GLib reference manual can be found at the GNOME developer site.
