<para>
Returns an associative array containing information about a user
referenced by a numeric user ID, passed in the
<parameter>uid</parameter> parameter.
</para>
<para>
The array elements returned are:
<table>
<title>The user information array</title>
<tgroup cols="2">
<thead>
<row>
<entry>Element</entry>
<entry>Description</entry>
</row>
</thead>
<tbody>
<row>
<entry>name</entry>
<entry>
The name element contains the username of the user. This is
a short, usually less than 16 character "handle" of the
user, not her real, full name.
</entry>
</row>
<row>
<entry>passwd</entry>
<entry>
The passwd element contains the user's password in an
encrypted format. Often, for example on a system employing
"shadow" passwords, an asterisk is returned instead.
</entry>
</row>
<row>
<entry>uid</entry>
<entry>
User ID, should be the same as the
<parameter>uid</parameter> parameter used when calling the
function, and hence redundant.
</entry>
</row>
<row>
<entry>gid</entry>
<entry>
The group ID of the user. Use the function
<function>posix_getgrgid</function> to resolve the group
name and a list of its members.
</entry>
</row>
<row>
<entry>gecos</entry>
<entry>
GECOS is an obsolete term that refers to the finger
information field on a Honeywell batch processing system.
The field, however, lives on, and its contents have been
formalized by POSIX. The field contains a comma separated
list containing the user's full name, office phone, office
number, and home phone number. On most systems, only the
user's full name is available.
</entry>
</row>
<row>
<entry>dir</entry>
<entry>
This element contains the absolute path to the
home directory of the user.
</entry>
</row>
<row>
<entry>shell</entry>
<entry>
The shell element contains the absolute path to the
executable of the user's default shell.
