<p>Here's how to store a password in the running secret service,
like gnome-keyring or ksecretservice.</p>
<p>Each stored password has a set of attributes which are later
used to lookup the password. The attributes should not contain
secrets, as they are not stored in an encrypted fashion.</p>
<p>These examples use <a class="link" href="c-examples.html#c-schema-example" title="C example: Define a password schema">the example
schema</a>.</p>
<p>This first example stores a password asynchronously, and is
appropriate for GUI applications so that the UI does not block.</p>

<p>This next example stores a password synchronously. The function
call will block until the password is stored. So this is appropriate for
non GUI applications.</p>
