+PR_Sleep
+========
+
+Causes the current thread to yield for a specified amount of time.
+
+
+Syntax
+------
+
+.. code::
+
+   #include <prthread.h>
+
+   PRStatus PR_Sleep(PRIntervalTime ticks);
+
+
+Parameter
+~~~~~~~~~
+
+:ref:`PR_Sleep` has the following parameter:
+
+``ticks``
+   The number of ticks you want the thread to sleep for (see
+   :ref:`PRIntervalTime`).
+
+
+Returns
+~~~~~~~
+
+Calling :ref:`PR_Sleep` with a parameter equivalent to
+``PR_INTERVAL_NO_TIMEOUT`` is an error and results in a ``PR_FAILURE``
+error.
+
+
+Description
+-----------
+
+:ref:`PR_Sleep` simply waits on a condition for the amount of time
+specified. If you set ticks to ``PR_INTERVAL_NO_WAIT``, the thread
+yields.
+
+If ticks is not ``PR_INTERVAL_NO_WAIT``, :ref:`PR_Sleep` uses an existing
+lock, but has to create a new condition for this purpose. If you have
+already created such structures, it is more efficient to use them
+directly.
+
+Calling :ref:`PR_Sleep` with the value of ticks set to
+``PR_INTERVAL_NO_WAIT`` simply surrenders the processor to ready threads
+of the same priority. All other values of ticks cause :ref:`PR_Sleep` to
+block the calling thread for the specified interval.
+
+Threads blocked in :ref:`PR_Sleep` are interruptible.
