When a language request has been received from a client, srv_langlen returns the length of the request buffer.
srv_langlen is also used to process language strings in cursor declare or update statements.
All or part of the request buffer can be accessed with srv_langcpy.
The request buffer can contain any string, including Transact-SQL statements. It is up to the Open Server application to process the string.
