.. include:: ../common.txt .. highlight:: c ******************************************************** Class BufferProxy API exported by pgyame.bufferproxy ******************************************************** src_c/bufferproxy.c =================== This extension module defines Python type :py:class:`pygame.BufferProxy`. Header file: src_c/include/pygame_bufferproxy.h .. c:var:: PyTypeObject *pgBufproxy_Type The pygame buffer proxy object type pygame.BufferProxy. .. c:function:: int pgBufproxy_Check(PyObject *x) Return true if Python object *x* is a :py:class:`pygame.BufferProxy` instance, false otherwise. This will return false on :py:class:`pygame.BufferProxy` subclass instances as well. .. c:function:: PyObject* pgBufproxy_New(PyObject *obj, getbufferproc get_buffer) Return a new :py:class:`pygame.BufferProxy` instance. Argument *obj* is the Python object that has its data exposed. It may be ``NULL``. Argument *get_buffer* is the :c:type:`pg_buffer` get callback. It must not be ``NULL``. On failure raise a Python error and return ``NULL``. .. c:function:: PyObject* pgBufproxy_GetParent(PyObject *obj) Return the Python object wrapped by buffer proxy *obj*. Argument *obj* must not be ``NULL``. On failure, raise a Python error and return ``NULL``. .. c:function:: int pgBufproxy_Trip(PyObject *obj) Cause the buffer proxy object *obj* to create a :c:type:`pg_buffer` view of its parent. Argument *obj* must not be ``NULL``. Return ``0`` on success, otherwise raise a Python error and return ``-1``.
