# 7.5.3 Function Objects
############################################################################
# There are a few functions specific to Python functions.
# PyFunctionObject
# The C structure used for functions.
# PyTypeObject PyFunction_Type
# This is an instance of PyTypeObject and represents the Python
# function type. It is exposed to Python programmers as
# types.FunctionType.
bint PyFunction_Check(object o)
# Return true if o is a function object (has type
# PyFunction_Type). The parameter must not be NULL.
object PyFunction_New(object code, object globals)
# Return value: New reference.
# Return a new function object associated with the code object
# code. globals must be a dictionary with the global variables
# accessible to the function.
# The function's docstring, name and __module__ are retrieved from
# the code object, the argument defaults and closure are set to
# NULL.
PyObject* PyFunction_GetCode(object op)
# Return value: Borrowed reference.
# Return the code object associated with the function object op.
PyObject* PyFunction_GetGlobals(object op)
# Return value: Borrowed reference.
# Return the globals dictionary associated with the function object op.
PyObject* PyFunction_GetModule(object op)
# Return value: Borrowed reference.
# Return the __module__ attribute of the function object op. This
# is normally a string containing the module name, but can be set
# to any other object by Python code.
PyObject* PyFunction_GetDefaults(object op)
# Return value: Borrowed reference.
# Return the argument default values of the function object
# op. This can be a tuple of arguments or NULL.
int PyFunction_SetDefaults(object op, object defaults)
# Set the argument default values for the function object
# op. defaults must be Py_None or a tuple.
# Raises SystemError and returns -1 on failure.
PyObject* PyFunction_GetClosure(object op)
# Return value: Borrowed reference.
# Return the closure associated with the function object op. This
# can be NULL or a tuple of cell objects.
int PyFunction_SetClosure(object op, object closure)
# Set the closure associated with the function object op. closure
# must be Py_None or a tuple of cell objects.
# Raises SystemError and returns -1 on failure.
