tibemsMsgConsumer_GetMsgListener
Function
Purpose
Get the message callback and closure data from a consumer.
C Declaration
tibems_status tibemsMsgConsumer_GetMsgListener( tibemsMsgConsumer msgConsumer, tibemsMsgCallback* callbackPtr, void** closure );
Parameters
| Parameter | Description |
|---|---|
msgConsumer
|
Get the listener from this consumer. |
callbackPtr
|
Store a pointer to the callback in this location. |
closure
|

Remarks
EMS C programs can implement a message listener as a callback function paired with closure data. This call extracts these items from a consumer object.
Your program implements the callback, and registers it by calling tibemsMsgConsumer_SetMsgListener. When a message arrives, the consumer calls the callback.
This call is not supported in COBOL.
