+<blockquote><pre>
+int sqlite3_load_extension(
+  sqlite3 *db,          /* Load the extension into this database connection */
+  const char *zFile,    /* Name of the shared library containing extension */
+  const char *zProc,    /* Entry point.  Derived from zFile if 0 */
+  char **pzErrMsg       /* Put error message here if not 0 */
+);
+</pre></blockquote>
+<p>
+This interface loads an SQLite extension library from the named file.</p>
+
+<p>The sqlite3_load_extension() interface attempts to load an
+<a href="../loadext.html">SQLite extension</a> library contained in the file zFile.  If
+the file cannot be loaded directly, attempts are made to load
+with various operating-system specific extensions added.
+So for example, if "samplelib" cannot be loaded, then names like
+"samplelib.so" or "samplelib.dylib" or "samplelib.dll" might
+be tried also.</p>
+
+<p>The entry point is zProc.
+zProc may be 0, in which case SQLite will try to come up with an
+entry point name on its own.  It first tries "sqlite3_extension_init".
+If that does not work, it constructs a name "sqlite3_X_init" where the
+X is consists of the lower-case equivalent of all ASCII alphabetic
+characters in the filename from the last "/" to the first following
+"." and omitting any initial "lib".
+The sqlite3_load_extension() interface returns
+<a href="../rescode.html#ok">SQLITE_OK</a> on success and <a href="../rescode.html#error">SQLITE_ERROR</a> if something goes wrong.
+If an error occurs and pzErrMsg is not 0, then the
+<a href="../c3ref/load_extension.html">sqlite3_load_extension()</a> interface shall attempt to
+fill *pzErrMsg with error message text stored in memory
+obtained from <a href="../c3ref/free.html">sqlite3_malloc()</a>. The calling function
+should free this memory by calling <a href="../c3ref/free.html">sqlite3_free()</a>.</p>
+
+<p>Extension loading must be enabled using
+<a href="../c3ref/enable_load_extension.html">sqlite3_enable_load_extension()</a> or
+<a href="../c3ref/db_config.html">sqlite3_db_config</a>(db,<a href="../c3ref/c_dbconfig_defensive.html#sqlitedbconfigenableloadextension">SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION</a>,1,NULL)
+prior to calling this API,
+otherwise an error will be returned.</p>
+
+<p><b>Security warning:</b> It is recommended that the
+<a href="../c3ref/c_dbconfig_defensive.html#sqlitedbconfigenableloadextension">SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION</a> method be used to enable only this
+interface.  The use of the <a href="../c3ref/enable_load_extension.html">sqlite3_enable_load_extension()</a> interface
+should be avoided.  This will keep the SQL function <a href="../lang_corefunc.html#load_extension">load_extension()</a>
+disabled and prevent SQL injections from giving attackers
+access to extension loading capabilities.</p>
+
+<p>See also the <a href="../lang_corefunc.html#load_extension">load_extension() SQL function</a>.
