src_c/bufferproxy.c

This extension module defines Python type pygame.BufferProxypygame object to export a surface buffer through an array protocol.

Header file: src_c/pgbufferproxy.h

PyTypeObject *pgBufproxy_Type

The pygame buffer proxy object type pygame.BufferProxy.

int pgBufproxy_Check(PyObject *x)

Return true if Python object x is a pygame.BufferProxy instance, false otherwise. This will return false on pygame.BufferProxy subclass instances as well.

PyObject* pgBufproxy_New(PyObject *obj, getbufferproc get_buffer)

Return a new pygame.BufferProxy instance. Argument obj is the Python object that has its data exposed. It may be NULL. Argument get_buffer is the pg_buffer get callback. It must not be NULL. On failure raise a Python error and return NULL.

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.

int pgBufproxy_Trip(PyObject *obj)

Cause the buffer proxy object obj to create a pg_buffer view of its parent. Argument obj must not be NULL. Return 0 on success, otherwise raise a Python error and return -1.
