<h1>C/C++ Indexer</h1>
<p>The C/C++ indexer uses the parser to create a database of your
source and header files that provides the basis for C/C++ search,
navigation features and parts of content assist.</p>
<p>The indexer runs on a background thread and reacts to resource
change events such as:
</p>
<ul>
  <li>C/C++ project creation/deletion</li>
  <li>Source files creation/deletion</li>
  <li>File imports</li>
  <li>Source file content changes</li>
</ul>
<p>It is possible to customize the behavior of the indexer through the
use of source folders or even turn it off completely. This customizable
behavior is available on a per-project basis (i.e. it is possible to
have different indexer settings for each project in your workspace). <br>
</p>
<p>CDT supports the contribution of additional indexers, with 2
indexers being provided with the default CDT release:<br>
</p>
<ul>
  <li>Fast C/C++ Indexer : provides fastest indexing capabilities - both
declarations and cross reference information. This is the recommended indexer.<br>
  </li>
  <li>Full C/C++ Indexer : provides even more accurate indexing capabilities at the cost of performance - both
declarations and cross reference information.<br>
  </li>
</ul>
