<a href="intro.html"><h2>SQLite C Interface</h2></a><h2>Enable Or Disable Extension Loading</h2><blockquote><pre>int sqlite3_enable_load_extension(sqlite3 *db, int onoff);
</pre></blockquote><p>
So as not to open security holes in older applications that are
unprepared to deal with <a href="../loadext.html">extension loading</a>, and as a means of disabling
<a href="../loadext.html">extension loading</a> while evaluating user-entered SQL, the following API
is provided to turn the <a href="../c3ref/load_extension.html">sqlite3_load_extension()</a> mechanism on and off.</p>
<p>Extension loading is off by default.
Call the sqlite3_enable_load_extension() routine with onoff==1
to turn extension loading on and call it with onoff==0 to turn
it back off again.

<a href="objlist.html">Objects</a>,
