Dcb Required input; type = DcbType
This parameter passes information about the

Alias Required input; type = AliasType
This parameter specifies the alias name of the

To find the first relationship, initialize the
first four bytes of parameter to a binary zero.
To find additional relationships, call this
intrinsic once for each relationship to be
returned.
EntityList Output; type = EntityListOutType
This parameter returns the names of all the
entities in the specified relationship on
