\modulesynopsis{The group database (\function{getgrnam()} and friends).}
|
|
|
|
|
|
This module provides access to the \UNIX{} group database.
|
|
It is available on all \UNIX{} versions.
|
|
|
|
Group database entries are reported as 4-tuples containing the
|
|
following items from the group database (see \code{<grp.h>}), in order:
|
|
\code{gr_name},
|
|
\code{gr_passwd},
|
|
\code{gr_gid},
|
|
\code{gr_mem}.
|
|
The gid is an integer, name and password are strings, and the member
|
|
list is a list of strings.
|
|
(Note that most users are not explicitly listed as members of the
|
|
group they are in according to the password database.)
|
|
\exception{KeyError} is raised if the entry asked for cannot be found.
|
|
|
|
It defines the following items:
|
|
|
|
\begin{funcdesc}{getgrgid}{gid}
|
|
Return the group database entry for the given numeric group ID.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{getgrnam}{name}
|
|
Return the group database entry for the given group name.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{getgrall}{}
|
|
Return a list of all available group entries, in arbitrary order.
|
|
\end{funcdesc}
