8 .. index:: object: function
10 There are a few functions specific to Python functions.
13 .. ctype:: PyFunctionObject
15 The C structure used for functions.
18 .. cvar:: PyTypeObject PyFunction_Type
20 .. index:: single: MethodType (in module types)
22 This is an instance of :ctype:`PyTypeObject` and represents the Python function
23 type. It is exposed to Python programmers as ``types.FunctionType``.
26 .. cfunction:: int PyFunction_Check(PyObject *o)
28 Return true if *o* is a function object (has type :cdata:`PyFunction_Type`).
29 The parameter must not be *NULL*.
32 .. cfunction:: PyObject* PyFunction_New(PyObject *code, PyObject *globals)
34 Return a new function object associated with the code object *code*. *globals*
35 must be a dictionary with the global variables accessible to the function.
37 The function's docstring, name and *__module__* are retrieved from the code
38 object, the argument defaults and closure are set to *NULL*.
41 .. cfunction:: PyObject* PyFunction_GetCode(PyObject *op)
43 Return the code object associated with the function object *op*.
46 .. cfunction:: PyObject* PyFunction_GetGlobals(PyObject *op)
48 Return the globals dictionary associated with the function object *op*.
51 .. cfunction:: PyObject* PyFunction_GetModule(PyObject *op)
53 Return the *__module__* attribute of the function object *op*. This is normally
54 a string containing the module name, but can be set to any other object by
58 .. cfunction:: PyObject* PyFunction_GetDefaults(PyObject *op)
60 Return the argument default values of the function object *op*. This can be a
61 tuple of arguments or *NULL*.
64 .. cfunction:: int PyFunction_SetDefaults(PyObject *op, PyObject *defaults)
66 Set the argument default values for the function object *op*. *defaults* must be
69 Raises :exc:`SystemError` and returns ``-1`` on failure.
72 .. cfunction:: PyObject* PyFunction_GetClosure(PyObject *op)
74 Return the closure associated with the function object *op*. This can be *NULL*
75 or a tuple of cell objects.
78 .. cfunction:: int PyFunction_SetClosure(PyObject *op, PyObject *closure)
80 Set the closure associated with the function object *op*. *closure* must be
81 *Py_None* or a tuple of cell objects.
83 Raises :exc:`SystemError` and returns ``-1`` on failure.
