An association is made between the resulting stream ID and the UID.</p> <p>If a stream is currently associated with the specified UID, then the existing stream is prepared for replacement.</p> <p>The following code fragment is typical. <codeph>store</codeph> is a pointer to an opened dictionary store. <codeph>RDictionaryWriteStream::AssignLC()</codeph> opens the stream associated with the UID <codeph>theuid</codeph> and prepares the stream for writing:</p> <codeblock id="GUID-48CA0DB4-44D8-5E1C-8211-1EB21F2CBACD" xml:space="preserve">...
