 .. c:function:: void PyErr_SetRaisedException(PyObject *exc)
 
-   Sets the exception currently being raised ``exc``.
-   If the exception is already set, it is cleared first.
-
-   ``exc`` must be a valid exception.
-   (Violating this rules will cause subtle problems later.)
-   This call consumes a reference to the ``exc`` object: you must own a
-   reference to that object before the call and after the call you no longer own
-   that reference.
-   (If you don't understand this, don't use this function. I warned you.)
+   Set *exc* as the exception currently being raised,
+   clearing the existing exception if one is set.
 
-   .. note::
-
-      This function is normally only used by code that needs to save and restore the
-      error indicator temporarily.  Use :c:func:`PyErr_GetRaisedException` to save
-      the current exception, e.g.::
-
-         {
-            PyObject *exc = PyErr_GetRaisedException();
-
-            /* ... code that might produce other errors ... */

-            PyErr_SetRaisedException(exc);
-         }
+      This call steals a reference to *exc*, which must be a valid exception.
