:mod:`resource` --- Resource usage information
==============================================

.. module:: resource
   :platform: Unix
   :synopsis: An interface to provide resource usage information on the current process.
.. moduleauthor:: Jeremy Hylton <jeremy@alum.mit.edu>
.. sectionauthor:: Jeremy Hylton <jeremy@alum.mit.edu>


This module provides basic mechanisms for measuring and controlling system
resources utilized by a program.

Symbolic constants are used to specify particular system resources and to
request usage information about either the current process or its children.

A single exception is defined for errors:


.. exception:: error

   The functions described below may raise this error if the underlying system call
   failures unexpectedly.


Resource Limits
---------------

Resources usage can be limited using the :func:`setrlimit` function described
below. Each resource is controlled by a pair of limits: a soft limit and a hard
limit. The soft limit is the current limit, and may be lowered or raised by a
process over time. The soft limit can neve
