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()`](os.xhtml#os.strerror "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.``EPERM`Operation not permitted `errno.``ENOENT`No such file or directory `errno.``ESRCH`No such process `errno.``EINTR`Interrupted system call. 参见 This error is
