At the C level, there is a function for testing: int PyObject_CheckReadBuffer(PyObject* o) http://docs.python.org/dev/api/abstract-buffer.html According to http://docs.python.org/dev/lib/non-essential-built-in-funcs.html a Python call to buffer(obj) will either return a buffer object or (tested) raise a TypeError: >>> buffer("123") <read-only buffer for 0x2b597d52b9c0, size -1, offset 0 at 0x2b597d52e340> >>> buffer(1) Traceback (most recent call last): File "<stdin>", line 1, in ?
