// Fills in second argument with the objectids of
// the dictionary entries of all groups to which
// the AcDbEntity belongs.

int GetGroups(AcDbEntity* pEnt, AcDbObjectIdArray& ids)
{
assert( pEnt != NULL );
AcDbVoidPtrArray* pReactors = pEnt->reactors();
if( pReactors != NULL )
{
for( int i = 0; i < pReactors->length(); i++ )
{
void* pV = pReactors->at(i);
if( pV != NULL && acdbIsPersistentReactor(pV) )
{
AcDbObjectId rId = acdbPersistentReactorObjectId(pV);
AcDbObjectPointer pGroup(rId, AcDb::kForRead);
if( pGroup.openStatus() == Acad::eOk )
ids.append(rId);
}
}
}
return ids.length();
