:mod:`errno` --- Standard errno system symbols
==============================================

.. module:: errno
   :synopsis: Standard errno system symbols.

----------------

This module makes available standard ``errno`` system symbols. The value of each
symbol is the corresponding integer value. The names and descriptions are
borrowed from :file:`linux/include/errno.h`, which should be pretty
all-inclusive.

.. data:: errorcode

Dictionary providing a mapping from the errno value to the string name in the
   underlying system.  For instance, ``errno.errorcode[errno.EPERM]`` maps to
   ``'EPERM'``.

To translate a numeric error code to an error message, use :func:`os.strerror`.

Of the following list, symbols that are not used on the current platform are not
defined by the module.  The specific list of defined symbols is available as
``errno.errorcode.keys()``.  Symbols available can include:

.. data:: EPERM

Operation not permitted

.. data:: ENOENT

No such file or directory

.. data:: ESRCH

No such process
