Hi there.
I'm writing a program that uses the Telnet protocol over TCP/IP
sockets. Of course, that has no bearing here, so I'll rephrase that
in Standard C++ :)
In essense, I'm trying to manipulate a data stream by using a custom
streambuf, so that I can access this as "just another iostream".
Alas, this data stream has a couple of "interesting" properties:

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).

Hi!
I recently decided to write a streambuf which handles streamed
IO to a device (ie. a socket).
Now, in an effort to move away from C-style IO error handling
(ie. if(read(..) == -1) ...), I decided to make my streambuf raise
exceptions upon device error states.
The code is supposed to run on several platforms, but there seems
to be some inconsistency between the different iostream
implementations. This led me to believe that I'm...

Hello!
Im trying to get a memstream object to work but it seems that I miss
something!
My expectation is to have one stream for input and another for output!
I also expect the streambuf to handle the allocation and deallocation of
memory automaticly!
Is it possible?
I have some C++ books but they all has poor coveridge on this topic!
Any examples on this topic!

Hey all,
I have read part seven of the FAQ and searched for an answer but can
not seem to find one.
I am trying to do the all too common verify the data type with CIN.
The code from the FAQ looks like this:

Can anyone provide me with a simple example of a streambuf filter for
character substitution that would function like this :
fout << filter << fin
All the filter would need to do is replace a specific character with
another.
Thanks for your help.

Hello,
my custom streambuf works fine with output via <<
and with input via .get()
but fails to input via >> or getline... any idea why?

I found an article
http://spec.winprog.org/streams/
as a starting point, but it seems to do alot of things that aren't very
standard at all. One particular problem is, that he is using a vector as his
input buffer and trys to assign an iterator to a char pointer.

class winzoostreambuffer : private LoggerConsole, public
sts::basic_streambuf<char, std::char_traits<char>>

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
