<para>
The <function>mysqli_data_seek</function> function seeks to an arbitrary result pointer
specified by the <parameter>offset</parameter> in the result set represented by
<parameter>result</parameter>. The <parameter>offset</parameter> parameter must be between
zero and the total number of rows minus one (0..<function>mysqli_num_rows</function> - 1).
</para>
<note>
<para>
This function can only be used with buffered results attained from the use of the
<function>mysqli_store_result</function> or <function>mysqli_query</function> functions.
