<h3><a name="intro">Introduction</a></h3>
Plugins for XChat are written in C. The interface aims to keep 100%
binary compatability. This means that if you upgrade XChat, you will
not need to recompile your plugins, they'll continue to work. The
interface doesn't depend on any structures and offsets, so compiler
versions shouldn't have an impact either. The only real requirement of
an XChat plugin, is that it define a "xchat_plugin_init" symbol. This
is your entry point function, see the example below. You should make
all your global variables and functions <i>static</i>, so that a symbol
is not exported. There is probably no harm in exporting these symbols,
but they are not necessary. Plugins are compiled as shared objects
(.so files), for example:
<pre>
gcc -Wall -O1 -shared myplugin.c -o myplugin.so
</pre>
<h3><a name="sample">Sample plugin</a></h3>
This simple plugin autoOps anyone who joins a channel you're in. It also
adds a new command /AUTOOPTOGGLE, which can be used to turn the feature ON
or OFF. Every XChat plugin must define an xchat_plugin_init function, this
is the normal entry point. xchat_plugin_deinit is optional.

<h3><a name="word">What's word and word_eol?</a></h3>
They are arrays of strings. They contain the parameters the user entered
for the particular command. For example, if you executed:
<pre>
/command NICK hi there
word[1] is command
word[2] is NICK
word[3] is hi
word[4] is there
word_eol[1] is command NICK hi there
word_eol[2] is NICK hi there
word_eol[3] is hi there
word_eol[4] is there
</pre>
These arrays are simply provided for your convenience. You are NOT allowed
to alter them. Both arrays are limited to 32 elements (index 31). word[0] and
word_eol[0] are reserved and should not be read.
<br><br><br>
<h3><a name="lists">Lists and Fields</a></h3>
Lists of information (DCCs, Channels, Userlist etc) can be retreived
with xchat_list_get. All fields are READ ONLY and must be copied if
needed for a long time after calling xchat_list_str. The types of lists and fields available are:
<blockquote>
"channels" - list of channels, querys and their servers.
<blockquote> <table border=1>
<tr bgcolor="#dddddd"><td>Name</td><td>Description</td><td>Type</td></tr>
<tr><td>channel</td><td>Channel or query name</td><td>string</td></tr>

<tr bgcolor="#dddddd"><td>Name</td><td>Description</td><td>Type</td></tr>
<tr><td>mask</td><td>Ignore mask. .e.g: *!*@*.aol.com</td><td>string</td></tr>
<tr><td>flags</td><td>Bit field of flags. 0=Private 1=Notice 2=Channel 3=Ctcp<br>

<h3><a name="win32">Plugins on Windows/Win32</a></h3>
Yes, it can be done. All you need is either MSVC or <a href="http://www.mingw.org">MINGW</a>. Simply compile your plugin as a DLL. You should have the
following files:
<ul>
<li><a href="http://xchat.org/docs/xchat-plugin.h">xchat-plugin.h</a> - Main Plugin header</li>
<li>plugin.c - Your plugin, you need to write this one :)</li>
<li>plugin.def - A simple text file containing the following:</li>
</ul>
<table bgcolor="#fefeb0">
<tr><td>EXPORTS</td></tr>
<tr><td> xchat_plugin_init</td></tr>
<tr><td> xchat_plugin_deinit</td></tr>
</table>
<br>To compile:
<pre>
cl -O1 -MD -G5 -DWIN32 -c plugin.c
link /DLL /out:plugin.dll /SUBSYSTEM:WINDOWS plugin.obj /def:plugin.def
</pre>
<font color=red>Caveat:</font> Plugins compiled on Win32 MUST have a
global variable called <b>ph</b>, which is the plugin_handle, much like
in the <a href="#sample">sample plugin</a> above.

equivalence of two nicknames.
