<h1 align=center>Data item count</h1>
|
|
<p>Once a cursor has been initialized to reference a particular key in the
|
|
database, it can be used to determine the number of data items that are
|
|
stored for any particular key. The <a href="../../api_c/dbc_count.html">DBcursor->c_count</a> method returns
|
|
this number of data items. The returned value is always one, unless
|
|
the database supports duplicate data items, in which case it may be any
|
|
number of items.
