## DESCRIPTION

           The  DB  library  is  a  family of classes that provides a
           modular programming interface to transactions and  record-
           oriented  file  access.   The library includes support for
           transactions, locking, logging and file page  caching,  as
           well  as  various  indexed  access  methods.   Many of the
           classes (e.g., the file page  caching  class)  are  useful
           independent of the other DB classes, although some classes
           are explicitly based on other classes (e.g.,  transactions
           and  logging).   For  a  general  description  of  the  DB
           package, see db_intro(3).

           This manual page describes the DbLsn class.

           A  DbLsn  is  a  "log  sequence  number"  that  is   fully
           encapsulated.  The class itself has no methods, other than
           a default constructor, so there is no way for the user  to
           manipulate  its data directly.  It is initialized and used
           by methods in  DbLog(3)  and  DbMpool(3).   These  methods
           always accept a pointer to a DbLsn.
