DESCRIPTION

11       To get access to the record definitions for the structures use:
12       -include_lib("cosNotification/include/*.hrl").
13
14       This module also exports the functions described in:
15
16         * CosNotifyComm_NotifySubscribe
17
18         * CosNotification_QoSAdmin
19
20         * CosNotifyFilter_FilterAdmin

33                 nected'{}}
34
35              This  operation connects a PullConsumer to the target object. If
36              a connection already exists an exception is raised.

68              A client use this operation to pull next event sequence of maxi‐
69              mum  length  MaxEvents.  This operation is blocking and will not
70              reply until the requested amount of events can be  delivered  or
71              the QoS property PacingInterval is reached. For more information
72              see the User's Guide.

106              This  operation  pulls  an  event sequence of the maximum length
107              MaxEvents, but do not block if the target object have no  events
108              to  forward.  The outparameter, HasEvent is true if the sequence
109              contain any events.

118              and terminate.
