GLib is a lower-level library that provides many useful definitions
and functions available for use when creating GDK and GTK
applications. These include definitions for basic types and their
limits, standard macros, type conversions, byte order, memory
allocation, warnings and assertions, message logging, timers, string
utilities, hook functions, a lexical scanner, dynamic loading of
modules, and automatic string completion. A number of data structures
(and their related operations) are also defined, including memory
chunks, 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 binary
trees, N-ary trees, quarks (a two-way association of a string and a
unique integer identifier), keyed data lists (lists of data elements
accessible by a string or integer id), relations and tuples (tables of
data which can be indexed on any number of fields), and caches.
A summary of some of GLib's capabilities follows; not every function,
data structure, or operation is covered here. For more complete
information about the GLib routines, see the GLib documentation. One
source of GLib documentation is http://www.gtk.org/.
If you are using a language other than C, you should consult your
language's binding documentation. In some cases your language may
have equivalent functionality built-in, while in other cases it may
not.
Definitions for the extremes of many of the standard types are:
G_MINFLOAT
G_MAXFLOAT
G_MINDOUBLE
G_MAXDOUBLE
G_MINSHORT
G_MAXSHORT
G_MININT
G_MAXINT
G_MINLONG
G_MAXLONG |
Also, the following typedefs. The ones left unspecified are dynamically set
depending on the architecture. Remember to avoid counting on the size of a
pointer if you want to be portable! E.g., a pointer on an Alpha is 8
bytes, but 4 on Intel 80x86 family CPUs.
char gchar;
short gshort;
long glong;
int gint;
char gboolean;
unsigned char guchar;
unsigned short gushort;
unsigned long gulong;
unsigned int guint;

double gdouble;
long double gldouble;
void* gpointer;
