16.15. errno
— 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 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:
-
errno.

¶ Operação não permitida

ENOENT
¶ No such file or directory
