The FAQ says nothing of the kind. Read it again. It recommends against
throwing built-in _types_ (like 'int' or 'char*'), not standard exceptions.
I'm not sure why I shouldn't throw something like std::domain_err or though -- if it does all that I want it to do.
By all means, throw it.

It did not say 'do not throw built-in exceptions' but 'do not throw
built-ins'. A built-in [type] is an 'int' or a 'char*'. At least how I
understood this. I do not see anything wrong with throwing an
std::runtime_ex ception, if it suits your needs

Ah, ok. They gave an example of throwing an exception object that
inherits from a standard exception, so I thought that's what the FAQ was
saying.
Thanks!

hi,
we are working on a c++ project which has a lot of thow list
specifications which in the end causes a lot of problems. now i would
like to remove them from the project. because the project has a size of
300000+ lines of code it is not so easy to do all of that manually.
therefore my question: is there a tool that you run on your sources and
which just converts the throw declarations into a comment? a tool that

Hello,
I was setting the primary key on a table which was a collection of 3 columns.
I mispelled the name of the second column when I built the array of collumns
when I created the array of collumns for the primary key. When I used the
"dt.primarykey(myArrayOfKeys)" no exception was thrown, and rather then the
primary key being a set of 3 columns, it was only a single column.
When you make this type of mistake when setting foreign keys,...

Hi!
<OT, background>
I am in a situation where I use two compilers from different

a misconfiguration, library conflict or my ignorance, with one
of the compilers I am having trouble related to libuwind.so,
which, to my knowledge, deals with the intricacies of unwinding
the stack upon an exception. Executables compiled with this
compiler crash with a SEGV after throw(), never...

Hi,
What does "throw" do? I understand that it throws an error when
certain exceptional situation happens. My guess is that this *ignores*
the error and *continues* so that it prevents the program from
crashing.
I just don't know where it throws the error to? It makes sense if it
outputs the error into a log file. Please let me know if my thoughts
are correct.

Hello,
It is said that if I implement a "swap" member function, then it
should never throw any exception. However, if I implement "swap" non-

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

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,...
