+<blockquote><pre>
+int sqlite3_close(sqlite3*);
+int sqlite3_close_v2(sqlite3*);
+</pre></blockquote>
+<p>
+The sqlite3_close() and sqlite3_close_v2() routines are destructors
+for the <a href="../c3ref/sqlite3.html">sqlite3</a> object.
+Calls to sqlite3_close() and sqlite3_close_v2() return <a href="../rescode.html#ok">SQLITE_OK</a> if
+the <a href="../c3ref/sqlite3.html">sqlite3</a> object is successfully destroyed and all associated
+resources are deallocated.</p>
+
+<p>Ideally, applications should <a href="../c3ref/finalize.html">finalize</a> all
+<a href="../c3ref/stmt.html">prepared statements</a>, <a href="../c3ref/blob_close.html">close</a> all <a href="../c3ref/blob.html">BLOB handles</a>, and
+<a href="../c3ref/backup_finish.html#sqlite3backupfinish">finish</a> all <a href="../c3ref/backup.html">sqlite3_backup</a> objects associated
+with the <a href="../c3ref/sqlite3.html">sqlite3</a> object prior to attempting to close the object.
+If the database connection is associated with unfinalized prepared
+statements, BLOB handlers, and/or unfinished sqlite3_backup objects then
+sqlite3_close() will leave the database connection open and return
+<a href="../rescode.html#busy">SQLITE_BUSY</a>. If sqlite3_close_v2() is called with unfinalized prepared
+statements, unclosed BLOB handlers, and/or unfinished sqlite3_backups,
+it returns <a href="../rescode.html#ok">SQLITE_OK</a> regardless, but instead of deallocating the database
+connection immediately, it marks the database connection as an unusable
+"zombie" and makes arrangements to automatically deallocate the database
+connection after all prepared statements are finalized, all BLOB handles
+are closed, and all backups have finished. The sqlite3_close_v2() interface
+is intended for use with host languages that are garbage collected, and
+where the order in which destructors are called is arbitrary.</p>
+
+<p>If an <a href="../c3ref/sqlite3.html">sqlite3</a> object is destroyed while a transaction is open,
+the transaction is automatically rolled back.</p>
+
+<p>The C parameter to <a href="../c3ref/close.html">sqlite3_close(C)</a> and <a href="../c3ref/close.html">sqlite3_close_v2(C)</a>
+must be either a NULL
+pointer or an <a href="../c3ref/sqlite3.html">sqlite3</a> object pointer obtained
+from <a href="../c3ref/open.html">sqlite3_open()</a>, <a href="../c3ref/open.html">sqlite3_open16()</a>, or
+<a href="../c3ref/open.html">sqlite3_open_v2()</a>, and not previously closed.
+Calling sqlite3_close() or sqlite3_close_v2() with a NULL pointer
+argument is a harmless no-op.
