Call Protocol

The tp_call Protocol

Instances of classes that set tp_call are callable.

PyObject *tp_call(PyObject *callable, PyObject *args, PyObject *kwargs);

The vectorcall protocol was introduced in PEP 590 as an additional protocol for making calls more efficient

typedef PyObject *(*vectorcallfunc)(PyObject *callable, PyObject *const *args, size_t nargsf, PyObject *kwnames)

PyObject *PyObject_Call(PyObject *callable, PyObject *args, PyObject *kwargs)
PyObject *PyObject_CallNoArgs(PyObject *callable)
PyObject *PyObject_CallOneArg(PyObject *callable, PyObject *arg)
PyObject *PyObject_CallObject(PyObject *callable, PyObject *args)
PyObject *PyObject_CallFunction(PyObject *callable, const char *format, ...)
PyObject *PyObject_CallMethod(PyObject *obj, const char *name, const char *format, ...)
PyObject *PyObject_CallFunctionObjArgs(PyObject *callable, ...)
PyObject *PyObject_CallMethodObjArgs(PyObject *obj, PyObject *name, ...)
PyObject *PyObject_CallMethodNoArgs(PyObject *obj, PyObject *name)
PyObject *PyObject_CallMethodOneArg(PyObject *obj, PyObject *name, PyObject *arg)
PyObject *PyObject_Vectorcall(PyObject *callable, PyObject *const *args, size_t nargsf, PyObject *kwnames)
PyObject *PyObject_VectorcallDict(PyObject *callable, PyObject *const *args, size_t nargsf, PyObject *kwdict)
