it should be possible to get an exception, I'd hope.

Perhaps instead of restricting what functions ctypes can use, we could
restrict what modules can use ctypes. For example, maybe only modules
in certain directories should be allowed to import ctypes.
And that's indeed the case. The test suite may use ctypes.

Hello all,
Hi this i my first post here. I would like to create a tkinter
toplevel window with a custom resize action based on a grid. From the
Tk docs it say you can do this but for the life of me i cannot figure
out how? In my app i wish for the main window t
Hi there
This is my first post to the list - please forgive me if this has been
addressed elsewhere.
I'm running MySQL 32-bit in Snow Leopard, and had MySQLdb working well.
I switched to 64-bit, rebuilt MySQLdb, and again it worked fine within
Python, but had to switch back to 32 bit - I'm u

Notice that it's not (only) the functions itself, but also the
parameters. It's absolutely easy to crash Python by calling a function
through ctypes that expects a pointer, and you pass an integer. The
machine code will dereference the pointer (trusting that it actually is
one), and crash.

ok... analogy: when using g++ to compile c++ code, would you place
use of "asm" statements into the same sort of foot-shooting category?
In a slightly different way, yes. There is no way of disabling inline
assembly in g++, so the analogy is not fully appropriate.
However, IIUC, using inlin

Would it be possible to write a program that converts a module that uses
ctypes to interface to a dll to a corresponding C extension program that
would compile to a drop in replacement extension module?
If implemented at all, I think the ctypes implementation itself could do
that. I.e. create al
