 |  | 
 | The \module{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. | 
 |  | 
 | The \module{nis} module defines the following functions: | 
 |  | 
 | \begin{funcdesc}{match}{key, mapname} | 
 | Return the match for \var{key} in map \var{mapname}, or raise an | 
 | error (\exception{nis.error}) if there is none. | 
 | Both should be strings, \var{key} is 8-bit clean. | 
 | Return value is an arbitrary array of bytes (may contain \code{NULL} | 
 | and other joys). | 
 |  | 
 | Note that \var{mapname} is first checked if it is an alias to another | 
 | name. | 
 | \end{funcdesc} | 
 |  | 
 | \begin{funcdesc}{cat}{mapname} | 
 | Return a dictionary mapping \var{key} to \var{value} such that | 
 | \code{match(\var{key}, \var{mapname})==\var{value}}. | 
 | Note that both keys and values of the dictionary are arbitrary | 
 | arrays of bytes. | 
 |  | 
 | Note that \var{mapname} is first checked if it is an alias to another | 
 | name. | 
 | \end{funcdesc} | 
 |  | 
 | \begin{funcdesc}{maps}{} | 
 | Return a list of all valid maps. | 
 | \end{funcdesc} | 
 |  | 
 |  | 
 | The \module{nis} module defines the following exception: | 
 |  | 
 | \begin{excdesc}{error} | 
 | An error raised when a NIS function returns an error code. | 
 | \end{excdesc} |
