<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.
