+    <para>
+      The <function>pam_prompt</function> function constructs a message
+      from the specified format string and arguments and passes it to the
+      conversation function as set by the service. Upon successful return,
+      <emphasis>response</emphasis> is set to point to a string
+      returned from the conversation function. This string is allocated
+      on heap and should be freed.
