Query: Will a MutexGuard object release before a function return value
is copied?
Consider the C++ code:
class MutexGuard //A familiar sort of class for making mutexes
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...

Hi
I have a function that needs to return value from some column in a table.
The column type is not known in advance. Is it possible for function to
return a value whose type would be determined at runtime? If so, how?
Thanks

I am trying to adopt a model for calling functions and checking their return
values. I'm following Scott Meyer's recommendation of not over-using
exceptions because of their potential overhead.
Here's the approach I'm currently looking at. I throw exceptions only from
constructors. Destructors, of course, do not throw exceptions. All other
functions return a signed integer. The values are all stored in one large
header file (as...

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,...
