+<blockquote><pre>
+sqlite3_value *sqlite3_value_dup(const sqlite3_value*);
+void sqlite3_value_free(sqlite3_value*);
+</pre></blockquote>
+<p>
+The sqlite3_value_dup(V) interface makes a copy of the <a href="../c3ref/value.html">sqlite3_value</a>
+object D and returns a pointer to that copy.  The <a href="../c3ref/value.html">sqlite3_value</a> returned
+is a <a href="../c3ref/value.html">protected sqlite3_value</a> object even if the input is not.
+The sqlite3_value_dup(V) interface returns NULL if V is NULL or if a
+memory allocation fails. If V is a <a href="../bindptr.html">pointer value</a>, then the result
+of sqlite3_value_dup(V) is a NULL value.</p>
+
+<p>The sqlite3_value_free(V) interface frees an <a href="../c3ref/value.html">sqlite3_value</a> object
+previously obtained from <a href="../c3ref/value_dup.html">sqlite3_value_dup()</a>.  If V is a NULL pointer
+then sqlite3_value_free(V) is a harmless no-op.
