2017-01-23io: change the QIOTask callback signatureDaniel P. Berrange1-1/+0
Currently the QIOTaskFunc signature takes an Object * for the source, and an Error * for any error. We also need to be able to provide a result pointer. Rather than continue to add parameters to QIOTaskFunc, remove the existing ones and simply pass the QIOTask object instead. This has methods to access all the other data items required in the callback impl. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
