This is an example for LBuffer::Copy(lpData, dwSize):

L_INT LBuffer__CopyExample(LBitmapBase& LeadBitmap)
{
   L_INT nRet;
   LBuffer LeadBuffer;
   LBuffer MyBuffer ;
   nRet =(L_INT)LeadBitmap.GetRow(&LeadBuffer,6);
   if(nRet < 1)
      return nRet;
   nRet =MyBuffer.Copy((L_CHAR  *)LeadBuffer.Lock(),LeadBuffer.GetSize());
   if(nRet !=SUCCESS)
      return nRet;
   LeadBuffer.Unlock();
   return SUCCESS;
