Illustrator SDK :: Finding Art By Name?

I have assigned ai::UnicodeString names to some art in my AI document.
This I have acheived using      sAIUIDUtils->SetArtNameOrUID()
 
For retreiving the art from document, I want to use the ai::UniCodeString names of the art.
 
error = sAIUIDPool->GetPool("anyName", &pool);           // The SDK reference says the 1st parameters is ignored, but error = 1346458189 after this steperror = sAIUIDPool->NewUIDREF(pool, myUnicodeName, &uidRef);error = sAIUIDUtils->GetReferencedArt(uidRef, &foundArt);
if(foundArt == NULL){ matchingArtFound = false;}
 
What is wrong with the above code to acheive : "Get the art, knowing its name" ? Is there any better way to do so ?
 
This unicode name is the one which we see in the attribute name "id" in the SVG  format of the AI document.
