NAME
       Proc::ProcessTable - Perl extension to access the unix process table

SYNOPSIS
         use Proc::ProcessTable;

         $p = new Proc::ProcessTable( 'cache_ttys' => 1 );
         @fields = $p->fields;
         $ref = $p->table;

DESCRIPTION
       Perl interface to the unix process table.

METHODS
       new Creates a new ProcessTable object. The constructor can take one flag:

           cache_ttys -- causes the constructor to look for and use a file that caches a mapping
           of tty names to device numbers, and to create the file if it doesn't exist (this file
           is /tmp/TTYDEVS by default). This feature requires the Storable module.

       fields
           Returns a list of the field names supported by the module on the current architecture.

       table
           Reads the process table and returns a reference to an array of
           Proc::ProcessTable::Process objects. Attributes of a process object are returned by
           accessors named for the attribute; for example, to get the uid of a process just do:

           $process->uid

           The priority and pgrp methods also allow values to be set, since these are supported
           directly by internal perl functions.

EXAMPLES
        # A cheap and sleazy version of ps
        use Proc::ProcessTable;

        $FORMAT = "%-6s %-10s %-8s %-24s %s\n";
        $t = new Proc::ProcessTable;
        printf($FORMAT, "PID", "TTY", "STAT", "START", "COMMAND");
        foreach $p ( @{$t->table} ){
          printf($FORMAT,
                 $p->pid,
                 $p->ttydev,
                 $p->state,
                 scalar(localtime($p->start)),
                 $p->cmndline);
        }


        # Dump all the information in the current process table
        use Proc::ProcessTable;

        $t = new Proc::ProcessTable;

        foreach $p (@{$t->table}) {
         print "--------------------------------\n";
         foreach $f ($t->fields){
           print $f, ":  ", $p->{$f}, "\n";
         }
        }
