<p>Any time before parsing is called, a log handler can be set
on the world object via the
<a class="link" href="raptor2-section-world.html#raptor-world-set-log-handler" title="raptor_world_set_log_handler ()"><code class="function">raptor_world_set_log_handler()</code></a>
method to report errors and warnings from parsing.
The method takes a user data argument plus a handler callback of type
<a class="link" href="raptor2-section-general.html#raptor-log-handler" title="raptor_log_handler ()"><span class="type">raptor_log_handler</span></a>
with a signature that looks like this:
</p>
<pre class="programlisting">
void
message_handler(void *user_data, raptor_log_message* message)
{
/* do something with the message */
}
</pre>
<p>
The handler gets the user data pointer as well as a
<a class="link" href="raptor2-section-general.html#raptor-log-message" title="raptor_log_message"><span class="type">raptor_log_handler</span></a>
pointer that includes associated location information, such as the
log level,
<a class="link" href="raptor2-section-locator.html#raptor-locator" title="raptor_locator"><span class="type">raptor_locator</span></a>,
and the log message itself. The <span class="emphasis"><em>locator</em></span>
structure contains full information on the details of where in the
file or URI the message occurred.
