+
+Initializes the runtime.
+
+
+Syntax
+------
+
+.. code::
+
+   #include <prinit.h>
+
+   void PR_Init(
+     PRThreadType type,
+     PRThreadPriority priority,
+     PRUintn maxPTDs);
+
+
+Parameters
+~~~~~~~~~~
+
+:ref:`PR_Init` has the following parameters:
+
+``type``
+   This parameter is ignored.
+``priority``
+   This parameter is ignored.
+``maxPTDs``
+   This parameter is ignored.
+
+
+Description
+-----------
+
+NSPR is now implicitly initialized, usually by the first NSPR function
+called by a program. :ref:`PR_Init` is necessary only if a program has
+specific initialization-sequencing requirements.
+
+Call :ref:`PR_Init` as follows:
+
+.. code::
+
+    PR_Init(PR_USER_THREAD, PR_PRIORITY_NORMAL, 0);
