 The highest-level function to do this is :c:func:`PyRun_SimpleString` which takes
 a single string argument to be executed in the context of the module
 ``__main__`` and returns ``0`` for success and ``-1`` when an exception occurred
-(including ``SyntaxError``).  If you want more control, use
+(including :exc:`SyntaxError`).  If you want more control, use
 :c:func:`PyRun_String`; see the source for :c:func:`PyRun_SimpleString` in
 ``Python/pythonrun.c``.
