5 \modulesynopsis{Standard errno system symbols.
}
8 This module makes available standard
\code{errno
} system symbols.
9 The value of each symbol is the corresponding integer value.
10 The names and descriptions are borrowed from
\file{linux/include/errno.h
},
11 which should be pretty all-inclusive.
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'
}.
19 To translate a numeric error code to an error message, use
20 \function{os.strerror()
}.
22 Of the following list, symbols that are not used on the current
23 platform are not defined by the module. The specific list of defined
24 symbols is available as
\code{errno.errorcode.keys()
}. Symbols
25 available can include:
