LASTLOG2(3)                 Programmers ManualLASTLOG2(3)

NAME        top

       lastlog2 - Y2038 safe version of lastlog library.

SYNOPSIS        top

#include <lastlog2.h>

DESCRIPTION        top

lastlog2reports 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 all 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.
