+PR_GetDefaultIOMethods
+======================
+
+Gets the default I/O methods table.
+
+
+Syntax
+------
+
+.. code::
+
+   #include <prio.h>
+
+   const PRIOMethods* PR_GetDefaultIOMethods(void);
+
+
+Returns
+~~~~~~~
+
+If successful, the function returns a pointer to a :ref:`PRIOMethods`
+structure.
+
+
+Description
+-----------
+
+After using :ref:`PR_GetDefaultIOMethods` to identify the default I/O
+methods table, you can select elements from that table with which to
+build your own layer's methods table. You may not modify the default I/O
+methods table directly. You can pass your own layer's methods table to
+:ref:`PR_CreateIOLayerStub` to create your new layer.
