<h3>API</h3>
<h4>Constants</h4>
Check to test if the plugin is active:
<pre><code>CLGS = true
</code></pre>
Defined severity levels:
<pre><code>CLGS_NOSEVERITY = 0
CLGS_INFO = 1
CLGS_NOTICE = 2
CLGS_WARNING = 3
CLGS_ERROR = 4
CLGS_FATALERROR = 5
</code></pre>
<h4>Functions</h4>
<pre><code>clgs_is_registered ( $category )
</code></pre>
<ul>
<li><code>string $category</code></li>
</ul>
returns <code>true</code> if <code>$category</code> is registered.
<pre><code>clgs_register ( $category, $description )
</code></pre>
registers <code>$category</code> as a log category. <code>$description</code> will be shown in the 
management page. 
It is good practice to use unique categories for each plugin that publishes 
log messages.

<li><code>string $description</code> can contain HTML same as comments (filtered by 
 wp_kses_data)</li>
</ul>
returns <code>false</code> if the category is already registered or it is too long.
<pre><code>clgs_clear ( $category )
</code></pre>
deletes all log entries of <code>$category</code>.
<ul>
<li><code>string $description</code> existing category</li>
</ul>
returns number of deleted entries or <code>false</code> if action failed.
<pre><code>clgs_unregister( $category );
</code></pre>
deletes all log entries and then removes <code>$category</code>.
<ul>
<li><code>string $description</code> existing category</li>
</ul>
returns <code>false</code> if false if action failed.
<pre><code>clgs_log( $category, $text, $severity = null, $user = null, $blog_id = null, $date = null );
</code></pre>
writes a new log entry in the specified category
<ul>
<li><code>string $description</code> a registered category name</li>
<li><code>string $text</code> the logged message, can contain HTML same as comments (filtered 
by <code>wp_kses_data</code>)</li>

 CLGS_NOCATEGORY</li>

defaults to current user (or a placeholder if none is logged in)</li>
<li><code>int $blog_id</code> blog id; if missing defaults to current blog</li>
