DDS4CCM_ — Return value of operations on MultiUpdater/MultiWriter/

A question, several of the methods on MultiUpdater/MultWriter return an
unsigned long for nb of instances update/written/etc. At the moment the
method succeeds all instances are updated, the caller has passed in the
sequence, so he knows which elements got updated. If it failed, we get an
exception with the index failed (so no return value). It looks that the
return value doesn't add a thing, why not make it void?
