: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
|
|
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:
|
|
|
|
