     utmpx, wtmpx - utmpx and wtmpx database entry formats

SYNOPSIS

     #include <utmpx.h>
     /var/adm/utmpx

DESCRIPTION

     The utmpx and wtmpx files are extended database  files  that
     have superseded the obsolete utmp and wtmp database files.

     The utmpx  database  contains  user  access  and  accounting
     information  for  commands  such  as  who(1),  write(1), and
     login(1). The wtmpx database contains the  history  of  user
     access and accounting information for the  utmpx database.

USAGE

     Applications should not access these databases directly, but
     should  use  the  functions  described  on the getutxent(3C)
     manual page to interact with the utmpx and  wtmpx  databases
     to ensure that they are maintained consistently.
