Hello,
I am trying to implement the buffer API for the JPype Python module.
Unfortunately the required type slots (Py_bf_getbuffer, Py_bf_releasebuffer)
are currently disabled due to the long since closed issue #10181. JPype is a
bridge module between Java and Python and as such it is

ever, if you're working with
multi-megabyte data buffers,it's more efficient and safer to use an
array view (ctypes or NumPy) on the returned buffer.
After studying the example you explained in your previous post replied
to Gregory Ewing, I had noticed that until today I was totally
confused with
c_char_p, which is a char * pointer.) However, if you're working with
multi-megabyte data buffers,it's more efficient and safer to use an
array view (ctypes or NumPy) on the returned buffer.
In most cases, you should free the returned pointer after you're

I'd like to create a native Python object that exposes the buffer

I have no experience writing extensions in C, but as I see it,
you're returning a new reference to self, so you'd need:
Py_INCREF(self);
If you don't, then a Py_DECREF inside the assignment operator
causes your polynomial to be garbage collected. Its heap slot
is later used for the unrelated buffer object you're seeing.
Hope this helps,

How do you pass a Python buffer() value as an argument to a ctypes
function, which expects a c_void_p argument? I keep getting TypeError:
ctypes.ArgumentError: argument 2: : wrong type

Thanks all, adding the 'rb' and 'wb' solved that test case.
The reason I read the file "the hard way" is that I'm testing why I

STRING is not just a pointer to wide characters. It is itself a
structure:
typedef struct _UNICODE_STRING {
USHORT Length;
USHORT MaximumLength;
PWSTR Buffer;
} UNICODE_STRING;
So, I think you want fields of ctypes.c_ulong, ctypes.c_ushort,
ctypes.c_ushort, and ctypes.c_wchar_p. M

Been digging ever since I posted this. I suspected that the response might

problem is I don't want any dependencies and I also don't need persistence
