if cancel() request is issued after the request was already complete, request success/failure completion will be reported and cancel() request ignored.
if the request was actually canceled, cancellation completion is reported.

virtual std::tr1::shared_ptr<Channel> epics::pvAccess::ChannelRequest::getChannel ( )

pure virtualinherited

Get a channel instance this request belongs to.

virtual void epics::pvAccess::ChannelRequest::lastRequest ( )

pure virtualinherited

Announce next request as last request.

When last request will be completed (regardless of completion status) the remote and local instance will be destroyed.

virtual void epics::pvAccess::ChannelProcess::process ( )

pure virtual
