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