Posted in a previous thread was some Python code for accessing Window's
Simple MAPI api using the ctypes module.
http://groups-beta.google.com/group/comp.lang.python/msg/56fa74cdba9b7be9
This Simple MAPI module was Ian's completed version of an example
I had posted in an earlier message. In it I had to set some pointer
fields in a C structure to NULL. I was not happy with the solution I
used so I made an inquiry on the ctypes-users...

hi all and before I start I apologise if I have this completely muddled
up but here goes.
I'm trying to call functions from a dll file in a python script but I
can't work out what functions are available. I'm using ctypes. I've
tried using dir(ctypes_object) but the resultant output looks like a
list of standard functions and not the ones I'm looking for.
Also how can I tell if the dll was written in C or C++ as I understand
C++ dlls...

I'm not able to build IP2Location's Python interface so I'm
trying to use ctypes to call its C interface. The functions
return a pointer to the struct below. I haven't been able to
figure out how I should declare the return type of the functions
and read the fields. Any hint is appreciated.
typedef struct
{
char *country_short;
char *country_long;

You're right the ctypes does seem more pythonesque; however I'm still stuck trying return all these parameters
that the c api uses. my ctypes code is below. It just quits running when I try to print

but I could sure use some help. my ctypes test code follows...

I have the impression that SWIG has multiple backends for different
languages. There is one for automating much of the work of producing an
extension module. I presume there could be one, if not already, that
produced Python/cytpe code instead of C code. That would be a nice

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
