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.
-
errno.
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:
