# tibems_IsConsumerMulticast

Function

## Purpose

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.

Check if a consumer can receive messages over multicast.

## C Declaration

    tibems_bool tibems_IsConsumerMulticast(
        tibemsMsgConsumer consumer,
        tibems_bool *isMulticast);

## Remarks

It is possible for a consumer to be a multicast consumer yet only receive messages over TCP. This may happen when the consumer is created on a wildcard destination that includes both unicast and multicast topics.

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