<p>Octave's group database functions return information in a structure
with the following fields.
<dl>
<dt><code>name</code><dd>The user name.
<br><dt><code>passwd</code><dd>The encrypted password, if available.
<br><dt><code>gid</code><dd>The numeric group id.
<br><dt><code>mem</code><dd>The members of the group.
</dl>
<p>In the descriptions of the following functions, this data structure is
referred to as a <var>grp_struct</var>.
