Gets a relationship set object that represents the Relationships part that stores relationships that have the part as their source.

Syntax

HRESULT GetRelationshipSet(
  [out, retval] IOpcRelationshipSet **relationshipSet
);

Parameters

[out, retval] relationshipSet

A pointer to a relationship set object that represents the Relationships part that stores all relationships that have the part as their source.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code	Description
S_OK	The method succeeded.
E_POINTER	The relationshipSet parameter is NULL.
Package Consumption error	An HRESULT error code from the Package Consumption Error Group.
Part URI error	An HRESULT error code from the Part URI Error Group.

Remarks

The definitive way to find a part of interest is by using a relationship type to find the relationship that has the part of interest as its target. The target's URI can then be resolved to a part name which is used to access the part.

For more information about using the relationship type to find a relationship and then a part of interest, see IOpcRelationshipSet and IOpcRelationship.
