.. c:function:: PyObject* PyEval_GetBuiltins()
.. c:function:: PyObject* PyEval_GetBuiltins(void)
Return a dictionary of the builtins in the current execution frame,
or the interpreter of the thread state if no frame is currently executing.
.. c:function:: PyObject* PyEval_GetLocals()
.. c:function:: PyObject* PyEval_GetLocals(void)
Return a dictionary of the local variables in the current execution frame,
or ``NULL`` if no frame is currently executing.
.. c:function:: PyObject* PyEval_GetGlobals()
.. c:function:: PyObject* PyEval_GetGlobals(void)
Return a dictionary of the global variables in the current execution frame,
or ``NULL`` if no frame is currently executing.
.. c:function:: PyFrameObject* PyEval_GetFrame()
.. c:function:: PyFrameObject* PyEval_GetFrame(void)
Return the current thread state's frame, which is ``NULL`` if no frame is
currently executing.
