libsecret uses standard the standard GCancellable idiom to cancel operations.
It is not necessary to check whether the keyring daemon is available before using it. It is started automatically.
Errors are returned as standard GError in the usual way. There are fewer errors that are worth handling in an intelligent way, exceptions are in the SecretError enumeration. It is not recommended to display any GError message returned by libsecret to the user. Most of the possible errors are DBus communication problems or similar.
