Hello everyone,
As far as I know, C function does not throw exception.
But Bjarne said in his book, section 14.8 Exception and Efficiency,
--------------------
In particular, an implementation knows that only a few standard C
library functions (such as atexit() and qsort()) can throw exceptions,
and it can take advantage of that fact to generate better code.
--------------------
What did he mean? C function could really throw exception? What
exception -- C++ exception or structured exception?
thanks in advance,
George 1 1406

There are no structured exceptions in C++ world (it's a MS Windows specific
thing), so Bjarne meant C++ exceptions.
atexit() and qsort() both take function pointers to callback function that
get called at some time and these functions could throw an exception. So
atexit() and qsort() can indirectly throw exceptions.

Dear all,
How can I handle correctly cascading exception?
I generally use to catch exception ib all my function.
This to identify each type the correct place that the
exception occurs. What could happen is that if an
exception occurs inside a function that call others
function, it happend that I could get a never ending loop
of exception routine calling other exception routines.

Hi
I have a problem with the Microsoft.ApplicationBlocks.ExceptionManagement? I
can't get it to work in RELEASE mode? If I run the project in debug mode
the block works fine but when I run the exe file it doesn't catch any
errors?
Does anyone know what my problem might be?

The std::exception class defined in the Standard C++ <exception> header
specifies that the constructors could throw any exception becuase they
do not have a throw() specification.
Why is that? Is this because there could be an exception thrown when
the code creates a std::exception? I would assume that is not the case.
However, if I want to create a new exception class, derived from
std::exception (say MyException) then how can I...

Hi,
I have many assert() call in my code, now I am considering to replace
them with exception. The reason I want to do this change is that with
the program going bigger and bigger, it is hard to test all the corner
cases, and thus assert() does not work as good as before. The problem
is if there are something really bad which was not captured by
assert(), then in runtime, most likely the program will crash. This is
the worst user...

Help,
I'm running VS.NET 2003 and when I try to start my application, I get the
"unhandled exception" dialog instead of the IDE highlighting the offending

the problem (and it a large class).
How can I get the IDE to take me to the offending line of code?

I wrote some sample code (see below) for nested exception throwing
i.e. my catch blocks are throwing exceptions of their own (for
simplicity I used standard exceptions). I am getting some extraneous
characters (St9) in my final output. Can anyone kindly help me
interpret that please?
Thanks,

Hi, all.
I've never been any good at handling exceptions... So I need your
help.
Within a try{ } block, I have to call a function that has to throw its
own exception. How should I go about doing this?
try {
checkNullHeader( sHeader, ref status );

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.

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.
