const has internal linkage in C++, but external linkage in C.
Am I right ?
But, linker reports multiply-defined error if the
following header is included in multiple .cpp files.
// test_const.h
#ifndef HEADER_TEST
#define HEADER_TEST

1. Are linkage convention and calling convention referring to the same
thing?
2. Does calling convention differ between languages C and C++?
3. How does calling convention differ between static and non-static class
member function?
4. Could it be possible to specify different calling convention for each
"global" or each class member function? Even in a single file scope?

Hello everyone,
As far as I understand, the 'inline' keyword is a hint for the compiler
to consider the function in question as a candidate for inlining, yes?
What happens when a function with extern linkage is inlined? Should the
compiler still export the function?
Or is an inlined function implicitly static?

The title says it all.
I can see the case where a function is to be called directly from C, the
name mangling will stuff this up.
But I can't see a reason why a template function can't be given extern
"C" linkage where it is to be assigned to a C function pointer.

I was just listing down various ways in which variables can be created

do static and inline functions or members have internal linkage? I have
been reading this newsgroup on google and found conflicting ideas. Can
someone please help me understand why in some places inline may have
external linkage while in others it has internal (from what I have read
in comments by people). Are there any (other) places where linkage is
ambiguous?

Dear Group,
The book of Bjarne Stroustrup in chapter 5.4.4 says the following
"The word static is one of the most overused words in C and C++. For
static data members it has both of the common meanings: static as in
"statically allocated" as opposed to on the stack or on the free store
and static as in "with restricted visibility" as opposed to with
external linkage. For member functions, static has the second
meaning."

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...

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,...
