channelDisconnect()

virtual void epics::pvAccess::ChannelBaseRequester::channelDisconnect ( bool destroy )

inlinevirtual

Notification when underlying Channel becomes DISCONNECTED or DESTORYED.

(re)connection is notified through a sub-class *Connect() method.

Any in-progress get()/put()/request()/start() is implicitly cancel()'d or stop()'d before this method is called.

Ownership of any PVStructures passed to completion callbacks (eg. ChannelGetRequester::getDone() ) is returned the operation

Parameters

destroy

true for final disconnect.

The requester must have a name.

Returns
