A consumer will use the APIs: --- Py_buffer *view; int ndim; const char *format; const Py_ssize_t *shape, *strides, *suboffsets; void *buf; view = PyBuffer_New(); PyObject_GetBuffer(obj, view, flags); ndim = PyBuffer_GetLayout(&format, &shape, &strides, &suboffsets); buf = PyBuffer_GetPointer(view, [...]); PyBuffer_Free(view); // also calls PyBuffer_Release() --- The API functions PyBuffer_FillInfo(), PyBuffer_FillInfoEx(), and PyBuffer_GetInternal() are for exporters (producers)-only. The exporter uses the PyBuffer_FillInfo*() in its Py_bf_getbuffer function to fill the view. It may use PyBuffer_GetInternal() in its Py_bf_releasebuffer function to access the internal field and to release additional resources. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45459> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
