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 classService 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
