utmp(4)

NAME

     utmp, wtmp - utmp and wtmp database entry formats

SYNOPSIS

     #include <utmp.h>
     /var/adm/utmp
     /var/adm/wtmp

DESCRIPTION

     The utmp and wtmp database files are  obsolete  and  are  no
     longer  present on the system.  They have been superseded by
     the extended database contained in the utmpx and wtmpx data-
     base files.  See utmpx(4).

     It is possible for /var/adm/utmp to reappear on the  system.
     This  would  most  likely occur if a third party application
     that still uses utmp recreates the file if it finds it miss-
     ing.  This  file should not be allowed to remain on the sys-
     tem. The user should investigate to determine which applica-
     tion is recreating this file.
