The construct
(void*)(((long)ptr + 3) & ~3)
worked well until now to enforce alignment of the pointer to long
boundaries. However, now VC++ warns about it, undoubtedly to help things
work on 64 bit machines, i.e. with 64 bit pointers.
In the early days of C, where there were problems with the size of int
being 16 or 32 bits, the response was that an int was guaranteed to hold
a pointer (yes, there were 64Kb address spaces at one time!)....

Is there an ANSI C or GNU C equivalent to the #pragma cancel_handler
provided in IBM's ILE C compiler?
http://publib.boulder.ibm.com/infocenter/iadthelp/v6r0/index.jsp?topic=/com.ibm.etools.iseries.pgmgd.doc/cpprog436.htm
What #pragma cancel_handler does is provide the building blocks for try
.... finally code block in a C function.
I am researching the degree of difficulty involved in porting ILE C
code from an IBM AS400 to GNU C.

I'm told that "#pragma once" has made it into the ISO standard for
either C or C++. I can't find any reference to that anywhere. If
it's true, do any of you have a reference I can use?
Thanks...

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,...
