# フレーム (frame) オブジェクト

type PyFrameObject
  Part of the Limited API (as an opaque struct).

  フレームオブジェクトを記述する際に用いられる、オブジェクトを表す C 構造体です。

  There are no public members in this structure.

  バージョン 3.11 で変更: The members of this structure were removed from the public C API. Refer to the What's New entry for details.

The `PyEval_GetFrame()` and `PyThreadState_GetFrame()` functions can be used to get a frame object.

See also Reflection.

PyTypeObject PyFrame_Type

  The type of frame objects. It is the same object as `types.FrameType` in the Python layer.

  バージョン 3.11 で変更: Previously, this type was only available after including `<frameobject.h>`.

int PyFrame_Check(PyObject *obj)

  Return non-zero if obj is a frame object.

  バージョン 3.11 で変更: Previously, this function was only available after including `<frameobject.h>`.

PyFrameObject *PyFrame_GetBack(PyFrameObject *frame)

  Get the frame next outer frame.

  Return a strong reference, or `NULL` if frame has no outer frame.

  Added in version 3.9.

PyObject *PyFrame_GetBuiltins(PyFrameObject *frame)

  Get the frame's `f_builtins` attribute.

  Return a strong reference. The result cannot be `NULL`.

  Added in version 3.11.

PyCodeObject *PyFrame_GetCode(PyFrameObject *frame)
  Part of the Stable ABI since version 3.10.

  Get the frame code.

  Return a strong reference.

  The result (frame code) cannot be `NULL`.

  Added in version 3.9.

PyObject *PyFrame_GetGenerator(PyFrameObject *frame)

  Get the generator, coroutine, or async generator that owns this frame, or `NULL` if this frame is not owned by a generator. Does not raise an exception, even if the return value is `NULL`.

  Return a strong reference, or `NULL`.

  Added in version 3.11.

PyObject *PyFrame_GetGlobals(PyFrameObject *frame)

  Get the frame's `f_globals` attribute.

  Return a strong reference. The result cannot be `NULL`.

  Added in version 3.11.

int PyFrame_GetLasti(PyFrameObject *frame)

  Get the frame's `f_lasti` attribute.

  Returns -1 if `frame.f_lasti` is `None`.

  Added in version 3.11.

PyObject *PyFrame_GetVar(PyFrameObject *frame, PyObject *name)

  Get the variable name of frame.

  - Return a strong reference to the variable value on success.

  - Raise `NameError` and return `NULL` if the variable does not exist.

  - Raise an exception and return `NULL` on error.

  name type must be a `str`.

  Added in version 3.12.

PyObject *PyFrame_GetVarString(PyFrameObject *frame, const char *name)

  Similar to `PyFrame_GetVar()`, but the variable name is a C string encoded in UTF-8.

  Added in version 3.12.

PyObject *PyFrame_GetLocals(PyFrameObject *frame)

  Get the frame's `f_locals` attribute (`dict`).

  Return a strong reference.

  Added in version 3.11.

int PyFrame_GetLineNumber(PyFrameObject *frame)
  Part of the Stable ABI since version 3.10.

  frame が現在実行している行番号を返します。

## Internal Frames

Unless using PEP 523, you will not need this.

struct _PyInterpreterFrame

  The interpreter's internal frame representation.

  Added in version 3.11.

PyObject *PyUnstable_InterpreterFrame_GetCode(struct _PyInterpreterFrame *frame);
  これは Unstable API. It may change without warning in minor releases.

  > Return a strong reference to the code object for the frame.

  Added in version 3.12.

int PyUnstable_InterpreterFrame_GetLasti(struct _PyInterpreterFrame *frame);
  これは Unstable API. It may change without warning in minor releases.

  Return the byte offset into the last executed instruction.

  Added in version 3.12.

int PyUnstable_InterpreterFrame_GetLine(struct _PyInterpreterFrame *frame);
  これは Unstable API. It may change without warning in minor releases.

  Return the currently executing line number, or -1 if there is no line number.

  Added in version 3.12.
