How to explore alias to folder?

[llprogrammer]

Hi All,
I can not found out how to explore programmatically child nodes of folder to which i have alias.

I use the following LAPI fucnctions to recursively walk through hierarchy of directories and aliases of Livelink Enterprise Workspace:

1.
LL_ListObjects(session, VolumID, ID, "DTree", 0, LL_PERM_CREATENODE, Childs);

2.
for (int i=0; i<NumberOfChilds; i++){
// get child #i
// if(child type is alias) {
LLLONG OriginalID=0;
status = LL_RecordGetInteger( child, "OriginalID", &OriginalID);
LLLONG OriginalVolID=0;
status = LL_RecordGetInteger( child, "OriginalVolID", &OriginalVolID);
// I want to obtain VolID and ID of referenced object in the code above.
//}
}

But LL_RecordGetInteger returns error: -2147418096
and OriginalVolID and OriginalID remains equal to 0.

Can anybody give me explain me what I do wrong?

Thanks in advance!

try this according to documentation.

ListReferences

This function returns a RecArray value object containing one Record of information for each shortcut (alias) or generation that references the specified object.

If that does not work try doing a query on the subtype
of reference mainly select * from dtree where subtype=1
subtype=1 are all the alias or shortcut objects

Well, if I called the wrong number, why did you answer the phone?

Hmm... how can I use ListReferences if I don't know VolumeID and ID of original (referenced) object? The problem is I want to get child nodes of original (referenced) object but I can not obtain its VolumeID and ID. I only have VolumeID and ID of alias object.

if you use GetObjectInfo on the ShortCut it returns a structure including :

OriginalID Integer
For a Shortcut (Alias) or Generation object, the object ID of the object it references; for all other objects, Undefined

OriginalVolID Integer
For a Shortcut (Alias) or Generation object, the volume ID of the object it references; for all other objects, Undefined

This should provide what you need.
