When Client-Library receives a registered procedure notification, it calls an application’s notification callback routine. Depending on the host client platform, the application may have to poll the network (with ct_poll) for Client-Library to invoke the notification callback. See “Receiving notifications asynchronously”.
The registered procedure’s name is available as the second parameter to the notification callback routine.
The arguments with which the registered procedure was called are available inside the notification callback as a parameter result set. To retrieve these arguments, an application:
Calls ct_con_props(CS_NOTIF_CMD) to retrieve a pointer to the command structure containing the parameter result set
Calls ct_res_info(CS_NUMDATA), ct_describe, ct_bind, ct_fetch, and ct_get_data to describe, bind, and fetch the parameters
