#include <dds_c_subscription.h>

Data Fields
DDS_Long	total_count
	The total number of instances that have been replaced during the life-span of the DDS_DataReader.
DDS_Long	total_count_change
	The incremental number of instances replaced since the last time the listener was called or the status was read.
DDS_InstanceHandle_t	last_instance_handle
	The instance that is being replaced.
DDS_InstanceHandle_t	last_replacement_instance
	Handle to the instance which last replaced an instance.
DDS_InstanceHandle_t	publication_handle
	Handle to the publisher which last replaced an instance.
DDS_Long	lost_samples
	The number of samples which where lost due to the instance being replaced. Note that this number is an approximation because the middleware does not keep track of how many samples were removed prior to the instance being replaced (or the state of the samples being replaced).
