SetReferenceL(const TDesC &, const TDesC &)

void	SetReferenceL	(	const TDesC &	aFromSuid,
			const TDesC &	aToSuid
		)

Creates an abstract reference linkage between the specified source and target object SUIDs.

leave: One of the system wide error codes, if a processing failure occurs.

Parameters

const TDesC & aFromSuid	The SUID of the source object from which the reference originates. param aToSuid The SUID of the target object to which the reference is made.
const TDesC & aToSuid

SetReferencesL(const TDesC &, const CDesCArray &)

void	SetReferencesL	(	const TDesC &	aParentSuid,
			const CDesCArray &	aToSuids
		)

Replaces the abstract reference links originating from the specified source object handle with the specified set of target object SUIDs.

leave: One of the system wide error codes, if a processing failure occurs.

Parameters
