<p>
There simply isn't space to cover all of glib's features in
this book. It's worth looking at glib whenever you find
yourself thinking, "There really <i class="EMPHASIS">
should</i> be a function that..."---<tt class=
"FILENAME">glib.h</tt> and the glib documentation on <a
href="http://www.gtk.org/" target="_top">
http://www.gtk.org/</a> are excellent resources.
</p>
<p>
Here's a brief list of features not already mentioned:
</p>
<ul>
<li>
<p>
<span class="STRUCTNAME">FLOAT_MAX</span>, etc.
equivalents for many numeric types.
</p>
</li>
<li>
<p>
Byte-order conversions.
</p>
</li>
<li>
<p>
<tt class="FUNCTION">g_memmove()</tt> is more portable
them <tt class="FUNCTION">memmove()</tt>.
</p>
</li>
<li>
<p>
<span class="STRUCTNAME">G_DIR_SEPARATOR</span> handles
Windows/UNIX differences.
</p>
</li>
<li>
<p>
<span class="STRUCTNAME">G_VA_COPY</span> copies a
<span class="STRUCTNAME">va_list</span> in a portable
way.
</p>
</li>
<li>
<p>
Numerous macros to permit the use of compiler
extensions (especially <tt class="APPLICATION">gcc</tt>
extensions) in a portable way.
</p>
</li>
<li>
<p>
Portable <tt class="FUNCTION">g_htonl()</tt> and other
host-to-network conversions.
</p>
</li>
<li>
<p>
A <span class="STRUCTNAME">GCache</span> generic cache
facility.
</p>
</li>
<li>
<p>
"Callback maintenance" routines---registering and
unregistering of callbacks.
</p>
</li>
<li>
<p>
The <tt class="FUNCTION">g_log()</tt> facility, allows
you to print warnings, messages, etc. with configurable
log levels and pluggable print routines.
</p>
</li>
<li>
<p>
<span class="STRUCTNAME">GMemChunk</span> facility
allows you to allocate a large pool of small memory
chunks, for efficiency gains compared to <tt class=
"FUNCTION">g_malloc()</tt>. Used in the <span class=
"STRUCTNAME">GList</span> implementation, for
example.
</p>
</li>
<li>
<p>
A timer facility.
</p>
</li>
<li>
<p>
Convenience/portability routines to get the user's home
directory, get the name of a <tt class="FILENAME">
/tmp</tt> directory, and similar tasks.
</p>
</li>
<li>
<p>
Filename manipulation, such as <tt class="FUNCTION">
g_basename()</tt> and <tt class="FUNCTION">
g_path_is_absolute()</tt>.
</p>
</li>
<li>
<p>
Bitfield manipulation.
</p>
</li>
<li>
<p>
Enhanced string and array classes. Pointer and byte
arrays.
</p>
</li>
<li>
<p>
<span class="STRUCTNAME">GQuark</span>---two way
mapping from strings to integer identifiers.
</p>
</li>
<li>
<p>
Routines to associate data with strings, or with
arbitrary pointers.
</p>
</li>
<li>
<p>
A lexical scanner.
</p>
</li>
<li>
<p>
Tab completions.
</p>
</li>
<li>
<p>
Calendrical/date-arithmetic functions.
</p>
</li>
<li>
<p>
A generic event loop abstraction, used to implement
GTK+'s event loop.
</p>
</li>
<li>
<p>
A portable threads abstraction.
</p>
</li>
</ul>
<p>
If you need some generally-useful routine that's not in
glib already, consider writing it in glib style and
contributing it to the library! You get free assistance
with design, debugging, and maintenance, and other
programmers benefit from the facility you've written. By
the time you read this, it's also possible that the feature
you want is already in the latest version of glib.
