Query: Will a MutexGuard object release before a function return value
is copied?
Consider the C++ code:

exception-safe

Hello All,
I know that when you pass an argument to a function (if you want let
the
function be able to change the value) then you can choose to pass the
argument by reference or a pointer to that argument.
Now my question is, why would you prefer to let a function return a
reference or a pointer ???
Consider the following with operator overloading. I suppose the
operator can be seen as a function (right ?)

Hi All:
I am trying to understand the C function call mechanism. Please bear with
me as I state what I know:
"every invocation of a function causes a frame for that function to be
pushed on stack. this contains the arguments this function was called
with, address to return to after return from this function (the location
in the previous stack frame), location of previous frame on stack (base or
start of this frame) and local variables...

Hello friends ~
We know that a C function will return a 32-bit value from a function
in %eax and a 64-bit value in %edx:%eax. But what about larger return
types, for example large structs? The only other spare register is
%ecx because %ebx needs to be preserved, but that only brings the
%possible total up to 96 bits. What happens after that?
Thanks for any information!

Can someone explain why this line
$bool = isset($_POST) && !empty(trim($_POST));
causes the error message "Can't use function return value in write
context". trim() returns a string. I test if it is empty. So what is
wrong with that?

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...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
