<h4>GlueGen Data Type Mapping</h4>
Gluegen has build-in types (terminal symbols) for:<br>
<br>
<table border="1">
<tr><th>type</th> <th>java bits</th> <th>native-x32 bits</th><th>native-x64 bits</th><th>type</th> <th>signed</th> <th>origin</th</tr>
<tr><th>void</th> <th> 0</th> <th> 0</th> <th> 0</th> <th>void</th> <th>void</th> <th>ANSI-C</th></tr>
<tr><th>char</th> <th> 8</th> <th> 8</th> <th> 8</th> <th>integer</th><th>signed or unsigned</th><th>ANSI-C</th></tr>
<tr><th>short</th> <th>16</th> <th>16</th> <th>16</th> <th>integer</th><th>signed or unsigned</th><th>ANSI-C</th></tr>
<tr><th>int</th> <th>32</th> <th>32</th> <th>32</th> <th>integer</th><th>signed or unsigned</th><th>ANSI-C</th></tr>
<tr><th>long</th> <th>64</th> <th>32</th> <th>32<sup>1</sup></th> <th>integer</th><th>signed or unsigned</th><th>Windows</th></tr>
<tr><th>long</th> <th>64</th> <th>32</th> <th>64</th> <th>integer</th><th>signed or unsigned</th><th>Unix</th></tr>
<tr><th>float</th> <th>32</th> <th>32</th> <th>32</th> <th>float</th> <th>signed</th> <th>ANSI-C</th></tr>
<tr><th>double</th> <th>64</th> <th>64</th> <th>64</th> <th>double</th> <th>signed</th> <th>ANSI-C</th></tr>
<tr><th>__int32</th> <th>32</th> <th>32</th> <th>32</th> <th>integer</th><th>signed or unsigned</th><th>windows</th></tr>

<tr><th>intptr_t</th> <th>64</th> <th>32</th> <th>64</th> <th>integer</th><th>signed</th> <th>stdint.h</th></tr>
<tr><th>size_t</th> <th>64</th> <th>32</th> <th>64</th> <th>integer</th><th>unsigned</th> <th>stddef.h</th></tr>

</table>

<p>
<b>Warning:</b> Try to avoid unspecified bit sized types, especially <b>long</b>, since it differs on Unix and Windows!<br>
<b>Note 1:</b> Type <b>long</b> will result in broken code on Windows, since we don't differentiate the OS and it's bit size is ambiguous.
</p>

<h4>GlueGen Platform Header Files</h4>
GlueGen provides convenient platform headers,<br>
which can be included in your C header files for native compilation and GlueGen code generation.<br>
<br>
Example:<br>
<pre>
#include <gluegen_stdint.h>
#include <gluegen_stddef.h>
uint64_t test64;
size_t size1;
ptrdiff_t ptr1;
</pre>
<br>
To compile this file you have to include the following folder to your compilers system includes, ie <code>-I</code>:<br>
<pre>
gluegen/make/stub_includes/platform
</pre>
<br>
To generate code for this file you have to include the following folder to your GlueGen <code>includeRefid</code> element:<br>
<pre>
gluegen/make/stub_includes/gluegen
</pre>
</p>
<p>
<h4>GlueGen Pre-Defined Macros</h4>
To identity a GlueGen code generation run, GlueGen defines the following macros:<br>
<pre>
#define __GLUEGEN__ 2
</pre>
