Function Documentation

DDS_CoherentSetInfo_equals()

DDS_Boolean DDS_CoherentSetInfo_equals	(	const struct DDS_CoherentSetInfo_t *	self,
		const struct DDS_CoherentSetInfo_t *	other
	)

Compares this CoherentSetInfo with another CoherentSetInfo for equality.

Parameters

self	<<in>> This CoherentSetInfo. Cannot be NULL.
other	<<in>> The other CoherentSetInfo to be compared with this GUID. Cannot be NULL.

Returns

DDS_BOOLEAN_TRUE if the two CoherentSetInfos have equal values, or DDS_BOOLEAN_FALSE otherwise.

DDS_CoherentSetInfo_copy()

void DDS_CoherentSetInfo_copy	(	struct DDS_CoherentSetInfo_t *	self,
		const struct DDS_CoherentSetInfo_t *	other
	)

Copies another CoherentSetInfo into this CoherentSetInfo.

Parameters

self	<<in>> This CoherentSetInfo. Cannot be NULL.
other	<<in>> The other CoherentSetInfo to be copied.

DDS_SampleInfo_get_sample_identity()

void DDS_SampleInfo_get_sample_identity	(	const struct DDS_SampleInfo *	self,
		struct DDS_SampleIdentity_t *	identity
	)

<<extension>> Retrieves the identity of the sample

The identity is composed of the DDS_SampleInfo::original_publication_virtual_guid and the DDS_SampleInfo::original_publication_virtual_sequence_number

DDS_SampleInfo_get_related_sample_identity

DDS_SampleInfo_get_related_sample_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 DDS_DataWriter 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
