.. 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(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(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(void)
Return the current thread state's frame, which is ``NULL`` if no frame is
currently executing.
See also :c:func:`PyThreadState_GetFrame`.
.. c:function:: PyFrameObject* PyFrame_GetBack(PyFrameObject *frame)
Get the *frame* next outer frame.
Return a strong reference, or ``NULL`` if *frame* has no outer frame.
*frame* must not be ``NULL``.
.. versionadded:: 3.9
.. c:function:: PyCodeObject* PyFrame_GetCode(PyFrameObject *frame)
Get the *frame* code.
Return a strong reference.
*frame* must not be ``NULL``. The result (frame code) cannot be ``NULL``.
.. versionadded:: 3.9
.. c:function:: int PyFrame_GetLineNumber(PyFrameObject *frame)
Return the line number that *frame* is currently executing.
*frame* must not be ``NULL``.
.. c:function:: const char* PyEval_GetFuncName(PyObject *func)
Return the name of *func* if it is a function, class or instance object, else the
name of *func*\s type.
.. c:function:: const char* PyEval_GetFuncDesc(PyObject *func)
Return a description string, depending on the type of *func*.
Return values include "()" for functions and methods, " constructor",
" instance", and " object". Concatenated with the result of
:c:func:`PyEval_GetFuncName`, the result will be a description of
*func*.
