<title>DESCRIPTION</title>
<para>
The <function>pam_get_item</function> function allows applications
and PAM service modules to access and retrieve PAM information
of <emphasis>item_type</emphasis>. Upon successful return,
<emphasis>item</emphasis> contains a pointer to the value of the
corresponding item. Note, this is a pointer to the
<emphasis>actual</emphasis> data and should
<emphasis remap="B">not</emphasis> be <emphasis>free()</emphasis>'ed or
over-written! The following values are supported for
<emphasis>item_type</emphasis>:
</para>
<xi:include xmlns:xi="http://www.w3.org/2001/XInclude" href="pam_item_types_std.inc.xml"/>
<para>
The following additional items are specific to Linux-PAM and should not be used in
portable applications:

<xi:include xmlns:xi="http://www.w3.org/2001/XInclude" href="pam_item_types_ext.inc.xml"/>
<para>
If a service module wishes to obtain the name of the user,
it should not use this function, but instead perform a call to
<citerefentry>
<refentrytitle>pam_get_user</refentrytitle><manvolnum>3</manvolnum>
</citerefentry>.
</para>
<para>
Only a service module is privileged to read the
authentication tokens, PAM_AUTHTOK and PAM_OLDAUTHTOK.
