Hi group,
I'm playing with a little generic linked list/stack library, and have a
little problem with the interface of the pop() function. If I used a
struct like this it would be simple:
struct node {
struct node *next;
void *data;
};

Hi NG,
I've read some time ago in this NG, that when you're writing a library
it can be good practice to use an opaque type to point to your
structures if the user doesn't need to modify the structure himself.
This way the internal structure of the lib can be changed, and the lib
can be recompiled, but the application using the lib doesn't need to be
recompiled.
But then there are two ways to define the opque type:

Hello to everybody,
I'm trying to write a small program which is meant to interact with an
sqlite database. My idea is to create once a database handler, which
happens to be an opaque pointer (a pointer to a struct which is not
defined anywhere, if I understood correctly). Now, if I had the
possibility of instantiating a concrete struct, I would create a
function like this:
struct sqlite& myDb()
{

Can anyone explain what's an opaque pointer and how it's implemented in
C?
I read about this concept in the book "C interfaces and
implementations".
Here's an example from the book (list.h - available from the website):

Is it possible to overlay a transparent watermark on an image -
dynamically?
I'd like the result to look like this example:
<http://www.cycletourist.com/temp/photo.php>
That is a bit of overkill, but you can see what I mean. The watermark
image (a png image) is included separately below the photo.
I tried using a class from phpclasses.org

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:

Overview:
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,...
