Service.clearSync

bool clearSync(secret.schema.Schema schema,  string[string]  attributes,  gio.cancellable.Cancellable cancellable =  null)

Remove unlocked items which match the attributes from the secret service.

The attributes should be a set of key and value string pairs.

If service is null, then secret.service.Service.getSync will be called to get the default secret.service.Service proxy.

This method may block indefinitely and should not be used in user interface threads.

`schema`	the schema for the attributes
`attributes`	the attribute keys and values
`cancellable`	optional cancellation object

whether items were removed or not
