|

|
5 .. module:: errno |
|
6 :synopsis: Standard errno system symbols. |
|
7 |
|
8 |
|
9 This module makes available standard ``errno`` system symbols. The value of each |
|
10 symbol is the corresponding integer value. The names and descriptions are |
|
11 borrowed from :file:`linux/include/errno.h`, which should be pretty |
|
12 all-inclusive. |
|
13 |
|
14 |
|
15 .. data:: errorcode |
|
16 |
|
17 Dictionary providing a mapping from the errno value to the string name in the |
|
18 underlying system. For instance, ``errno.errorcode[errno.EPERM]`` maps to |
|
19 ``'EPERM'``. |
|
20 |
|
21 To translate a numeric error code to an error message, use :func:`os.strerror`. |
|
22 |
|
23 Of the following list, symbols that are not used on the current platform are not |
|
24 defined by the module. The specific list of defined symbols is available as |
|
25 ``errno.errorcode.keys()``. Symbols available can include: |
|
