NAME

utmpx, wtmpx - utmpx and wtmpx database entry formats

SYNOPSIS

#include <utmpx.h>

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superseded the obsolete utmp and wtmp database files.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.
