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 the following flags:

	   enable_ttys -- causes the constructor to use the tty determination code, which is the default behavior.  Setting this to 0 diables this
	   code, thus preventing the module from traversing the device tree, which on some systems, can be quite large and/or contain invalid
	   device paths (for example, Solaris does not clean up invalid device entries when disks are swapped).  If this is specified with
	   cache_ttys, a warning is generated and the cache_ttys is overridden to be false.

	   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
";
	$t = new Proc::ProcessTable;
	printf($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 "--------------------------------
";
	 foreach $f ($t->fields){
	   print $f, ":  ", $p->{$f}, "
";
	 }
	}
