Hi all,
I am using mysql C API in my C++ project. I am using
mysql-4.1.4-gamma and gcc 3.2.2.
Problem with this code is that when add_data(i) is called second time
SEGMENTATION FAULT occurs at mysql_real_query(). First time it
executes the add_data() function successfully.

I'm having a problem calling a C function from a publicly available
library file. To get the code to compile, I had to declare the
function as an external C function as follows.
extern "C" lib_function(....);
But when I run my C++ program, I get a segmentation fault in one
of the library functions (not the function I directly called but
one a few levels down in the calling hierarchy). According to
the user manual provided with the...

Hi!
I am new in C. I try to use dynamical allocation fuction malloc( ) and
realloc( ).
I found something strange.
After several calling realloc( ), the malloc( ) will give me a
Segmentation fault.
If I just call realloc( ) once before calling malloc( ), it is OK.
Why?
I am trying to read some double-typed items from infile and save them

I have not been able to find much information on the rules for macros. I want to be able to call a macro from outside it's

Hello,
I have class in which I am allocating space for a double array in the
constructor. I use the double array twice in one of the methods and then
delete that array in the class's destructor.
Now, that delete operation is giving me a segmentation fault. If I move
the allocation and deletion of the pointer within the method where the
pointer is being is used, it works okay ... but then another pointer
gives a segmentation fault in...

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...

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,...
