<h3>Berkeley DB Reference Guide: Access Methods</h3>
<p>
<h1 align=center>Database cursors</h1>
<p>
The <a href="../../api_c/Db/cursor.html">DB->cursor</a> function is the standard function for opening
a cursor into a database.
<p>
Once a database cursor has been opened there are four additional standard
access method operations that can be performed. Each of these operations
is performed using a function that is referenced from the returned cursor
handle. The four operations are as follows:
<p>
<dl compact>
<p><dt><a href="../../api_c/Dbc/get.html">DBcursor->c_get</a><dd>Retrieve a record
<dt><a href="../../api_c/Dbc/put.html">DBcursor->c_put</a><dd>Store a record
<dt><a href="../../api_c/Dbc/del.html">DBcursor->c_del</a><dd>Delete a record
<dt><a href="../../api_c/Dbc/close.html">DBcursor->c_close</a><dd>Close the cursor
</dl>
