Hi!
I was planning to wrap a socket inside an iostream, to achieve
something like this:
TCPSocket s(..);
s << "Hello!" << endl;
Information on the web seems to be a bit scarce on how to do this.
I have understood that there is a relation between streambuf and
iostream, where one should be able to extend streambuf and override
the underflow/overflow functions (and do send()/recv() for example).

I know I keep asking similar questions, but I really want to do this
at least sort of right. Not to mention I got no on-group replies to
my previous post :( I desperately want an interface that can allow
classes that implement it to act sort of like streams, but I just
can't seem to get everything I want...
class Writable
{
protected:
ostringstream outbuf; // or should I use private inheritance?

Hello,
I posted previously under the thread:
How to break this up into streambuf/ostream
I've asked our library to get "C++ IOStreams and Locales..." by A.
Langer et al. Meantime, I've looked at the C++ standard (ISO/IEC
14882) from the web to get a grip on the relationship between ostream
methods and streambuf methods: flush(), operator<<(), sputc(),

Hi,
My objective is to add enable & disable functionality to
the ofstream class. I want to have a log file where I
can disable and enable output to it. When my first
tests pass, I want to disable the annotations written
to the log file, but enable the text from the newer
test cases.
I've searched the C++ newsgroups and the FAQ-Lite

I've recently been using a class for directing output to both a file and
the screen. I copied it from this website:
http://www.talkaboutprogramming.com/group/comp.lang.c++/messages/812299.html
This works perfectly on windows platforms, but for some reason I can't get
it to compile on my SCO machine.
I get the following errors:
tee.h:27: syntax error before `('

Hello all,
I'm working on writing my own streambuf classes (to use in my custom
ostream/isteam classes that will handle reading/writing data to a
mmap'd file).
When reading from the mmap file, I essentially have a char buffer in my
streambuf class, that I'm registering with setp(). on an overflow()
call, I simply copy the contents of the buffer into the mmap'd file via
memcpy().

Can anybody help me understand what i'm doing wrong or what I'm missing? Is there anyother good and commendable C++ program I can use (free) from the internet like Dev C++? I'm having trouble doing basic compiling on this new Dev C++, when i try to print something like:
#include<iostream.h>
using namespace std;
int main ()
{
cout << "Hello to the world" << endl;
system("PAUSE")
return 0;

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,...

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