LASTLOG2(3)                   Programmers Manual                   LASTLOG2(3)

NAME
       lastlog2 - Y2038 safe version of lastlog library.

SYNOPSIS
       #include <lastlog2.h>

DESCRIPTION
       lastlog2 reports the last login of a given user or of all users who did
       ever login on a system.

       It's using sqlite3 as database backend. Data is only collected via a
       PAM module, so that every tools can make use of it, without modifying
       existing packages.  The output is as compatible as possible with the
       old lastlog implementation.  By default the database will be written as
       /var/lib/lastlog/lastlog2.db.  The size of the database depends on the
       amount of users, not how big the biggest UID is.
