channelDisconnect()

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

inlinevirtualinherited

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.

Definition at line 198 of file pvAccess.h.

getDone()

virtual void epics::pvAccess::GetFieldRequester::getDone ( const epics::pvData::Status & status, epics::pvData::FieldConstPtr const & field )

pure virtual

Check status.isOk() to determine success.

On success the 'field' will be non-NULL. On failure 'field' will be NULL.

Parameters

status	Completion status.
field	The Structure for the request.
