## NAME
    [Sys::Utmp::Utent](https://www.chedong.com/phpMan.php/perldoc/Sys%3A%3AUtmp%3A%3AUtent/markdown) - represent a single utmp entry

## SYNOPSIS
      use [Sys::Utmp](https://www.chedong.com/phpMan.php/perldoc/Sys%3A%3AUtmp/markdown);

      my $utmp = [Sys::Utmp](https://www.chedong.com/phpMan.php/perldoc/Sys%3A%3AUtmp/markdown)->new();

      while ( my $utent =  $utmp->getutent() )
      {
         if ( $utent->user_process )
         {
            print $utent->ut_user,"\n";
         }
       }

       $utmp->endutent;

## DESCRIPTION
    As described in the [Sys::Utmp](https://www.chedong.com/phpMan.php/perldoc/Sys%3A%3AUtmp/markdown) documentation the getutent method returns an object of the type
    [Sys::Utmp::Utent](https://www.chedong.com/phpMan.php/perldoc/Sys%3A%3AUtmp%3A%3AUtent/markdown) which provides methods for accessing the fields in the utmp record. There are
    also methods for determining the type of the record.

    The access methods relate to the common names for the members of the C struct utent - those
    provided are the superset from the Gnu implementation and may not be available on all systems:
    where they are not they will return the empty string.

    ut_user
        Returns the use this record was created for if this is a record for a user process. Some
        systems may return other information depending on the record type. If no user was set this
        will be the empty string. If tainting is switched on with the '-T' switch to perl then this
        will be 'tainted' as it is possible that the user name came from an untrusted source.

    ut_id
        The identifier for this record - it might be the inittab tag or some other system dependent
        value.

    ut_line
        For user process records this will be the name of the terminalor line that the user is
        connected on.

    ut_pid
        The process ID of the process that created this record.

    ut_type
        The type of the record this will have a value corresponding to one of the constants (not all
        of these may be available on all systems and there may well be others which should be
        described in the getutent manpage or in /usr/include/utmp.h ) :

        ACCOUNTING - record was created for system accounting purposes.
        BOOT_TIME - the record was created at boot time.
        DEAD_PROCESS - The process that created this record has terminated.
        EMPTY - record probably contains no other useful information.
        INIT_PROCESS - this is a record for process created by init.
        LOGIN_PROCESS - this record was created for a login process (e.g. getty).
        NEW_TIME - record created when the system time has been set.
        OLD_TIME - record recording the old tme when the system time has been set.
        RUN_LVL - records the time at which the current run level was started.
        USER_PROCESS - record created for a user process (e.g. a login )

        for convenience [Sys::Utmp::Utent](https://www.chedong.com/phpMan.php/perldoc/Sys%3A%3AUtmp%3A%3AUtent/markdown) provides methods which are lower case versions of the
        constant names which return true if the record is of that type.

    ut_host
        On systems which support this the method will return the hostname of the host for which the
        process that created the record was started - for example for a telnet login. If taint
        checking has been turned on (with the -T switch to perl ) then this value will be tainted as
        it is possible that a remote user will be in control of the DNS for the machine they have
        logged in from. ( see perlsec for more on tainting )

    ut_time
        The time in epoch seconds wt which the record was created.

## BUGS
    Probably. This module has been tested on Linux, Solaris, FreeBSD ,SCO Openserver and SCO
    UnixWare and found to work on those platforms. If you have difficulty building the module or it
    doesnt behave as expected then please contact the author including if appropriate your
    /usr/include/utmp.h
