New submission from STINNER Victor <victor.stin...@haypocalc.com>: http://docs.python.org/py3k/c-api/arg.html contains some ambiguous (string or Unicode object) definitions: what is a string? what is an unicode object? Is it a string or not? The problem is that the documentation is for Python2: the code was changed, but not the documentation. I think that it can be replaced by (unicode objet) with lower U to be consistent with (bytes object).
--- There are two functions: getbuffer() and convertbuffer(). getbuffer(): pb=arg->ob_type->tp_as_buffer - if pb->bf_getbuffer is not NULL: call PyObject_GetBuffer(arg, view, PyBUF_SIMPLE) and PyBuffer_IsContiguous(view, 'C') - if pb->bf_getbuffer is NULL: call convertbuffer() convertbuffer() calls PyObject_GetBuffer(arg, &view, PyBUF_SIMPLE). --- "s#", "y", "z" formats use convertbuffer() "s", "y*", "z*" formats uses getbuffer(). "t" format reimplements convertbuffer(). "w*" format calls PyObject_GetBuffer(arg, (Py_buffer*)p, PyBUF_WRITABLE) and PyBuffer_IsContiguous((Py_buffer*)p, 'C'). "w" and "w#" formats call PyObject_GetBuffer(arg, &view, PyBUF_SIMPLE). I think that all these cases should be factorized in one unique function. Is it a bug, or functions using "s#", "y", "z", "t" formats do really support discontinious buffers?
