errno — Standard errno system symbols (original) (raw)
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 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 aserrno.errorcode.keys(). Symbols available can include:
errno.EPERM¶
