<p>libsecret uses standard the standard <a href="https://developer.gnome.org/gio/unstable/GCancellable.html"><span class="type">GCancellable</span></a> idiom
to cancel operations.</p>
<p>It is not necessary to check whether the keyring daemon is
available before using it. It is started automatically.</p>
<p>Errors are returned as standard <a href="https://developer.gnome.org/glib/unstable/glib-Error-Reporting.html#GError"><span class="type">GError</span></a> in the usual way.
There are fewer errors that are worth handling in an intelligent way,
exceptions are in the <a class="link" href="libsecret-SecretError.html#SecretError" title="enum SecretError"><span class="type">SecretError</span></a> enumeration. It is not recommended
to display any <a href="https://developer.gnome.org/glib/unstable/glib-Error-Reporting.html#GError"><span class="type">GError</span></a> message returned by libsecret to the user. Most
of the possible errors are DBus communication problems or similar.</p>
<p>Replacements for related libgnome-keyring functions and types
are described below:
