+    <title>DESCRIPTION</title>
+    <para>
+      The <function>pam_start</function> function creates the PAM context
+      and initiates the PAM transaction. It is the first of the PAM
+      functions that needs to be called by an application. The transaction
+      state is contained entirely within the structure identified by this
+      handle, so it is possible to have multiple transactions in parallel.
+      But it is not possible to use the same handle for different
+      transactions, a new one is needed for every new context.
+    </para>
+
+    <para>
+      The <emphasis>service_name</emphasis> argument specifies the name
+      of the service to apply and will be stored as PAM_SERVICE item in
+      the new context. The policy for the service will be read from the
+      file <filename>/etc/pam.d/service_name</filename> or, if that file
+      does not exist, from <filename>/etc/pam.conf</filename>.
+    </para>
+
+    <para>
+       The <emphasis>user</emphasis> argument can specify the name
+       of the target user and will be stored as PAM_USER item. If
+       the argument is NULL, the module has to ask for this item if
+       necessary.
+    </para>
+
+    <para>
+       The <emphasis>pam_conversation</emphasis> argument points to
+       a <emphasis>struct pam_conv</emphasis> describing the
+       conversation function to use. An application must provide this
+       for direct communication between a loaded module and the
+       application.
+    </para>
+
+    <para>
+       Following a successful return (PAM_SUCCESS) the contents of
+       <emphasis>pamh</emphasis> is a handle that contains the PAM
+       context for successive calls to the PAM functions. In an error
+       case is the content of <emphasis>pamh</emphasis> undefined.
+    </para>
+
+    <para>
+      The <emphasis>pam_handle_t</emphasis> is a blind structure and
+      the application should not attempt to probe it directly for
+      information. Instead the PAM library provides the functions
+      <citerefentry>
+        <refentrytitle>pam_set_item</refentrytitle><manvolnum>3</manvolnum>
+      </citerefentry> and
+      <citerefentry>
+        <refentrytitle>pam_get_item</refentrytitle><manvolnum>3</manvolnum>
+      </citerefentry>.
+      The PAM handle cannot be used for multiple authentications at the
+      same time as long as <function>pam_end</function> was not called on
+      it before.
+    </para>
+
+    <para>
+      The <function>pam_start_confdir</function> function behaves
+      like the <function>pam_start</function> function but it also
+      allows setting <emphasis>confdir</emphasis> argument with
+      a path to a directory to override the default
+      (<filename>/etc/pam.d</filename>) path for service policy
+      files. If the <emphasis>confdir</emphasis> is NULL, the function
+      works exactly the same as <function>pam_start</function>.
