Description

This function fills in graph with a completed graph of xrefs in the database pointed to by pHostDb.

Ghost references appear when there are unresolved xrefs in a drawing. Ghosts are the unresolved xref's last known outgoing references (that is, its nested xrefs.) To determine outgoing references of a node, see the AcDbGraphNode::numOut() and AcDbGraphNode::out() methods.

There is no distinction between ghost references and non-ghost references in the graph. However, any outgoing edge of a node whose status is not AcDb::kResolved is a ghost reference. Use the AcDbXrefGraphNode::xrefStatus() function to query a node's status.

Returns Acad::eOk if successful.
