virtual void epics::pvDatabase::ChannelPutLocal::cancel ( )

inlinevirtual

Cancel any pending request. Completion will be reported via request's response callback:

• 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.
