"nis" --- Interface to Sun's NIS (Yellow Pages)
***********************************************

バージョン 3.11 で非推奨、バージョン 3.13 で削除予定: The "nis" module
is deprecated (see **PEP 594** for details).

======================================================================

The "nis" module gives a thin wrapper around the NIS library, useful
for central administration of several hosts.

Because NIS exists only on Unix systems, this module is only available
for Unix.

Availability: not Emscripten, not WASI.

This module does not work or is not available on WebAssembly platforms
"wasm32-emscripten" and "wasm32-wasi". See WebAssembly プラットフォー
ム for more information.

The "nis" module defines the following functions:

nis.match(key, mapname, domain=default_domain)

   Return the match for *key* in map *mapname*, or raise an error
   ("nis.error") if there is none. Both should be strings, *key* is
   8-bit clean. Return value is an arbitrary array of bytes (may
   contain "NULL" and other joys).

   Note that *mapname* is first checked if it is an alias to another
   name.

   The *domain* argument allows overriding the NIS domain used for the
   lookup. If unspecified, lookup is in the default NIS domain.

nis.cat(mapname, domain=default_domain)

   Return a dictionary mapping *key* to *value* such that "match(key,
   mapname)==value". Note that both keys and values of the dictionary
   are arbitrary arrays of bytes.

   Note that *mapname* is first checked if it is an alias to another
   name.

   The *domain* argument allows overriding the NIS domain used for the
   lookup. If unspecified, lookup is in the default NIS domain.

nis.maps(domain=default_domain)

   Return a list of all valid maps.

   The *domain* argument allows overriding the NIS domain used for the
   lookup. If unspecified, lookup is in the default NIS domain.

nis.get_default_domain()

   Return the system default NIS domain.

The "nis" module defines the following exception:

exception nis.error

   An error raised when a NIS function returns an error code.
