Function pulsar_sys::pulsar_consumer_redeliver_unacknowledged_messages

pub unsafe extern "C" fn pulsar_consumer_redeliver_unacknowledged_messages(
    consumer: *mut pulsar_consumer_t
)

Redelivers all the unacknowledged messages. In Failover mode, the request is ignored if the consumer is not active for the given topic. In Shared mode, the consumers messages to be redelivered are distributed across all the connected consumers. This is a non blocking call and doesn't throw an exception. In case the connection breaks, the messages are redelivered after reconnect.
