+PR_AttachThread
+===============
+
+.. container:: blockIndicator obsolete obsoleteHeader
+
+   | **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+   | This feature is obsolete.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.
+
+Associates a :ref:`PRThread` object with an existing native thread.
+
+
+Syntax
+------
+
+.. code::
+
+   #include <pprthread.h>
+
+   PRThread* PR_AttachThread(
+      PRThreadType type,
+      PRThreadPriority priority,
+      PRThreadStack *stack);
+
+
+Parameters
+~~~~~~~~~~
+
+:ref:`PR_AttachThread` has the following parameters:
+
+``type``
+   Specifies that the thread is either a user thread
+   (``PR_USER_THREAD``) or a system thread (``PR_SYSTEM_THREAD``).
+``priority``
+   The priority to assign to the thread being attached.
+``stack``
+   The stack for the thread being attached.
+
+
+Returns
+~~~~~~~
+
+The function returns one of these values:
+
+-  If successful, a pointer to a :ref:`PRThread` object.
+-  If unsuccessful, for example if system resources are not available,
+   ``NULL``.
+
+
+Description
+-----------
+
+You use :ref:`PR_AttachThread` when you want to use NSS functions on the
+native thread that was not created with NSPR. :ref:`PR_AttachThread`
+informs NSPR about the new thread by associating a :ref:`PRThread` object
+with the native thread.
+
+The thread object is automatically destroyed when it is no longer
+needed.
+
+You don't need to call :ref:`PR_AttachThread` unless you create your own
+native thread. :ref:`PR_Init` calls :ref:`PR_AttachThread` automatically for
+the primordial thread.
+
+.. note::
+
+   **Note**: As of NSPR release v3.0, :ref:`PR_AttachThread` and
+   :ref:`PR_DetachThread` are obsolete. A native thread not created by NSPR
+   is automatically attached the first time it calls an NSPR function,
+   and automatically detached when it exits.
+
+In NSPR release 19980529B and earlier, it is necessary for a native
+thread not created by NSPR to call :ref:`PR_AttachThread` before it calls
+any NSPR functions, and call :ref:`PR_DetachThread` when it is done calling
+NSPR functions.
