Function Documentation

DDS_SampleIdentity_equals()

DDS_Boolean DDS_SampleIdentity_equals	(	const struct DDS_SampleIdentity_t *	self,
		const struct DDS_SampleIdentity_t *	other
	)

Compares this sample identity with another sample identity for equality.

Parameters

self	<<in>> This sample identity.
other	<<in>> The other sample identity to be compared with this sample identity.

Returns

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

DDS_WriteParams_reset()

void DDS_WriteParams_reset

(

struct DDS_WriteParams_t *

self

)

Resets all the fields to their default values.

This operation is useful to reset all the fields to their automatic value when DDS_WriteParams_t::replace_auto is enabled and the same params instance is used in multiple calls to FooDataWriter_write_w_params

Variable Documentation

writer_guid

struct DDS_GUID_t DDS_SampleIdentity_t::writer_guid

16-byte identifier identifying the virtual GUID.
