Function Documentation

void DDS_SampleInfo_get_sample_identity ( const struct DDS_SampleInfo self,
struct DDS_SampleIdentity_t identity 
)
void DDS_SampleInfo_get_related_sample_identity ( const struct DDS_SampleInfo self,
struct DDS_SampleIdentity_t related_identity 
)

<<extension>> Retrieves the identity of a sample related to this one

A sample can be logically related to another sample, when the DDSDataWriter wrote it using DDS_WriteParams_t::related_sample_identity. By default, a sample does not have a related sample, and this operation returns DDS_UNKNOWN_SAMPLE_IDENTITY.

The related identity is composed of the DDS_SampleInfo::related_original_publication_virtual_guid and the DDS_SampleInfo::related_original_publication_virtual_sequence_number
