Detailed Description

<<eXtension>> GUID type and defines.

Function Documentation

DDS_Boolean DDS_GUID_equals	(	const struct DDS_GUID_t *	self,
		const struct DDS_GUID_t *	other
	)

Compares this GUID with another GUID for equality.

Parameters

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

Returns

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

int DDS_GUID_compare	(	const struct DDS_GUID_t *	self,
		const struct DDS_GUID_t *	other
	)

Compares two GUIDs.

Parameters

self	<<in>> GUID to compare. Cannot be NULL.
other	<<in>> GUID to compare. Cannot be NULL.

Returns

If the two GUIDs are equal, the function returns 0. If self is greater than other the function returns a positive number; otherwise, it returns a negative number.

void DDS_GUID_copy	(	struct DDS_GUID_t *	self,
		const struct DDS_GUID_t *	other
	)

Copies another GUID into this GUID.

Parameters

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

Variable Documentation

struct DDS_GUID_t DDS_GUID_AUTO

Indicates that RTI Connext should choose an appropriate virtual GUID.

If this special value is assigned to DDS_DataWriterProtocolQosPolicy::virtual_guid or DDS_DataReaderProtocolQosPolicy::virtual_guid, RTI Connext will assign the virtual GUID automatically based on the RTPS or physical GUID.

struct DDS_GUID_t DDS_GUID_UNKNOWN

Unknown GUID.
