+   | **Obsolete**
+   | This feature is obsolete. Although it may still work in some
+     browsers, its use is discouraged since it could be removed at any
+     time. Try to avoid using it.
+
+The opaque :ref:`PRThreadStack` structure is only used in the third
+argument "``PRThreadStack *stack``" to the :ref:`PR_AttachThread` function.
+The '``stack``' argument is now obsolete and ignored by
+:ref:`PR_AttachThread`. You should pass ``NULL`` as the 'stack' argument to
+:ref:`PR_AttachThread`.
