When Exception handling disabled compiler still spits out "C++ exception
handler used." Why is that?
Why does it ask for "Specify /EHsc"?
Thanks!

It's telling you that you're trying to compile code that requires exception
handling with exception handling disabled. Either change the code (in this
case, it's the standard library, so you can't really do that), or enable
exception handling.

Thanks Carl.
By specifying "/EHsc", the compile error gone. So, in this case, what
"/EHsc" switch does here to solve the problem? Is it enabling exception
handling? What if exception handling has to be disabled and we have to use
the standard library, what shall we do then?

You cannot use the standard library without exceptions. You can, however,
use a library a lot like the standard library without exceptions. I believe
that Dinkumware's Unabridged Library (see http://www.dinkumware.com/libdual_vc.html) can be used with exceptions
disabled.

Hi,
I am an absolute newbie to Exception Handling, and I am trying to
retrofit exception handling to a LOT of C++ code that I've written
earlier. I am just looking for a bare-bones, low-tech exception
handling mechanism which will allow me to pass character information
about an error and its location from lower-level classes.
Can you please critique the following exception handling mechanism in
terms of my requirements ?

bool read(std::fstream& stream, u32& value);
or this:

I had a long and heated discussion with other developers on my team on when
it makes sense to throw an exception and when to use an alternate solution.
The .NET documentation recommends that an exception should be thrown only in
exceptional situations. It turned out that each of my colleagues had their
own interpretation about what an "exceptional situation" may actually be.
First of all, myself I’m against using exceptions extensively,...

Hi all,
I don't think a solution exists, but maybe there is some option in Visual
Studio that I do not know about.
When developping (or debugging), I like to set the "exceptions" option to
"break when the error is thrown", even for handled exceptions, because a
general purpose error handler usually handles all unexpected exceptions.
A side effect of that is that a break also happens when an exception occurs

How do I know which methods will throw exception when I am using FCL or other

I am developer of mostly native Windows applications and now .Net. After

documentation not clear on which methods will throw exception or what
exceptions can be expected. Jave APIs clearly define exceptions that can be
expected and enforces that we handle them.

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:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
