Notas

The buffer manager maintains a list of buffer types. Each buffer type definition contains the number of columns, the data type properties of each column, whether space is allocated that holds status information for the column, and how the columns are initialized when a new instance of the buffer type is created. This method is used to register a new buffer type with the manager. Once a buffer type has been defined, the returned ID of the buffer type is used when calling CreateBuffer. If a buffer definition is found that matches the parameters of this method, then its ID is returned. Otherwise, a new definition is created.
