The name element contains the name of the group. This is
a short, usually less than 16 character "handle" of the
group, not the real, full name.
The passwd element contains the group's password in an
encrypted format. Often, for example on a system employing
"shadow" passwords, an asterisk is returned instead.
Group ID, should be the same as the
parameter used when calling the
function, and hence redundant.
This consists of an array of
string's for all the members in the group.
