Adding 128-bit integer support

Fil Mackay — Wed, 06 Nov 2013 23:16:45 -0000

Can the 128-bit integer type be added to ctypes please? This seems like a big gap, given the popularity of this type within C/C++ compilers now.

Creating a restype supporting type

Jens Rantil — Thu, 26 Mar 2009 15:14:05 -0000

Hi,

Adding support for classes to be sent as an argument using the argtypes attribute and from_param(...) method seems pretty straight forward. Can a similar extension be done to support the restype attribute, or will the errcheck attribute be needed to do this conversion on the result?

More specifically I'd like to convert from ctypes arrays to NumPy arrays on the fly when calling a DLL function.

Thanks,

Jens

Add automatic variable generation to xml2py.py

Michal J. Gajda — Wed, 28 Feb 2007 11:38:10 -0000

xml2py.py doesn't seem to generate code for uninitialized variables. Since it may be crucial for library interface (see errno.h), I attach the crude patch that does that.

Add version info to DLL

Michael Kleehammer — Mon, 24 Jul 2006 15:22:29 -0000

It appears that an MSI-based upgrade that include
_ctypes.pyd did not upgrade the file from 996 to 999.
I assume it is because there was no version information
in the DLL.

This would be a big help.

Byte ordering

nicolas pinault — Fri, 04 Nov 2005 15:00:07 -0000

I need to access data structures which are in
big-endian format. I would like to be able to declare
and use Structures which manage this automaticaly. A
keyword could say the structure contains big-endian
data. When accessing this structure fields, byte
ordering would be done automaticaly.

SAFEARRAY

Luca Casagrande — Fri, 26 Nov 2004 09:46:17 -0000

I need for implementation of SAFEARRAY type.
In fact there are a lot of methods that use this type.

The problem is the following:

I use the readtlb.py tool for translate a Type Libary into
a python file; the result is a file in which the COM types
are translated according to the ctypes rules. However
the SAFEARRAY type is not recognized by the python
interpreter and I can't instantiate the class(es). Looking
in depth in to the ctypes module there is no evidence of
the SAFEARRAY Implementation.

Thanks

add support for accessing functions via pointer

Patrick Mueller — Thu, 30 Sep 2004 13:14:06 -0000

I have a requirement to be able to call functions that
I can only get to via pointer. ctypes itself does not
appear to support this, but _ctypes does. I ended up
doing something like below, which appears to work fine.
I'd like to see first class support for this in ctypes
itself. Would also need to support the Windows variant
as well (but probably not the Python one).

import ctypes
import _ctypes

#--------------------------------------------------------------------
#
#--------------------------------------------------------------------
class FunctionPtr(_ctypes.CFuncPtr):
_flags_ = _ctypes.FUNCFLAG_CDECL
_restype_ = ctypes.c_int

#--------------------------------------------------------------------
#
#--------------------------------------------------------------------
functionPtr = 0 # get a pointer to the function somehow

function = FunctionPtr(functionPtr)

result = function(arg1,arg2)
