aaApi_CreateAssociation usage

I didn't find a sample with aaApi_CreateAssociation, what are params LPCWSTR  lpctstrName,  LPCWSTR  lpctstrDesc 

I guess the latter is just a description, but what is lpctstrName? does it have to be something special or unique?

I want to check in a DWG document and xref, where the xref should be associated with the DWG.
