Standard errno system symbols
=============================

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 `linux/include/errno.h', which should be
pretty all-inclusive.

`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
`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:
