L_INT LAnnAudioClip_GetTextExample(LAnnAudioClip  * pAnnObject) 
{ 
   L_INT nRet; 
 
   L_TCHAR  *pText; /* The object's text */ 
   L_SIZE_T TextLength; /* Length of the object's text */ 
 
   LBuffer LeadBuffer ; 
 
   /* Get the length of the current text */ 
 
   TextLength = pAnnObject->GetTextLen(); 
 
   /* Add six characters to the length for our new text */ 
 
   TextLength += 6; 
 
   nRet = LeadBuffer.Reallocate((DWORD)TextLength*sizeof(L_TCHAR)); 
   if(nRet != SUCCESS) 
      return nRet; 
 
   pText = (L_TCHAR  *)LeadBuffer.Lock() ; 
 
   /* Get the current text */ 
 
   nRet = pAnnObject->GetText(pText, &TextLength); 
   if(nRet != SUCCESS) 
      return nRet; 
 
   /* Add " - New" to the end of the current text */ 
 
   lstrcat(pText,TEXT(" - New")); 
 
   nRet = pAnnObject->SetText(pText,0); 
   if(nRet != SUCCESS) 
      return nRet;
