These include definitions for basic types and theirlimits, standard macros, type conversions, byte order, memoryallocation, warnings and assertions, message logging, timers, stringutilities, hook functions, a lexical scanner, dynamic loading ofmodules, and automatic string completion. A number of data structures(and their related operations) are also defined, including memorychunks, doubly-linked lists, singly-linked lists, hash tables, strings(which can grow dynamically), string chunks (groups of strings),arrays (which can grow in size as elements are added), balanced binarytrees, N-ary trees, quarks (a two-way association of a string and aunique integer identifier), keyed data lists (lists of data elementsaccessible by a string or integer id), relations and tuples (tables ofdata which can be indexed on any number of fields), and caches.</P><P>A summary of some of GLib's capabilities follows; not every function,data structure, or operation is covered here.  For more completeinformation about the GLib routines, see the GLib documentation. Onesource of GLib documentation is <AHREF="http://www.gtk.org/"TARGET="_top">http://www.gtk.org/</A>.</P><P>If you are using a language other than C, you should consult yourlanguage's binding documentation. In some cases your language mayhave equivalent functionality built-in, while in other cases it maynot.</P><DIVCLASS="SECT1"><H1CLASS="SECT1"><ANAME="SEC-DEFINITIONS">22.1.
