# tibems_SetMulticastEnabled

Function

Warning: Along with the multicast feature, this function was deprecated in software release 8.3.0 and will no longer be supported in future releases.

## Purpose

Set whether message consumers subscribed to multicast-enabled topics in the EMS client application will receive messages over multicast.

## C Declaration

    tibems_status tibems_SetMulticastEnabled(
        tibems_bool enabled);

## Parameters

Parameter | Description
--- | ---
`enabled` | When true, multicast is enabled for the client. When false, multicast is disabled and the client application will receive all messages over TCP.

## Remarks

When enabled, message consumers subscribed to a multicast-enabled topic will receive messages over multicast. By default, multicast is enabled.

`tibems_SetMulticastEnabled` overrides both the EMS server and factory settings that enable multicast.

This call is not supported in COBOL, and is not supported on z/OS and IBM i systems.
