Old thread: >>105621602

What are you working on, /g/?

Threadly reminder.

have:
>TCP server
>TCP client with GUI button
>button triggers even to send TCP message to server
>client socket is opened in blocking mode so that it can block on recv to get the reply immediately

problem:
>if I kill and then reopen the server, the client does not reconnect as it's waiting for the button even before sending, and it doesn't receive until it sends
>if I switch to non-blocking mode I can detect the disconnect but I have to run the loop really fast which is wasteful or not fast enough and I don't get the reply as quickly as in blocking mode

what do? I guess I could create another thread for reads and use blocking mode and let that thread detect the disconnect but I heard more thread = bad for networking, try to keep it to 1

>registry dumber doesn't know how to mmap in C++
Not that you can ever mmap since you use OS for toddlers that holds your hand at every step, doesn't even let you overallocate, so you call VirtualAlloc constantly, while I just malloc 1ULL << 46 and it works.

>I just malloc
Sure thing, retard.

Clock's a-ticking.

recv / recvfrom / recvmsg

All three calls return the size of the message on successful
completion. If a message is too long to fit in the supplied
buffer, excess bytes may be discarded depending on the type of
socket the message is received from.


what does this mean? If I'm using a nonblocking socket and intentionally provide a buffer with less room than bytes that have arrived, does it return the size of the entire message, including the ones that did not get placed in buffer, or only the ones that were placed in buffer?

>>105651402
Size written to the buffer.

>>105651402
It depends whether you're talking about a stream (TCP) or datagram (UDP) socket. TCP is always reliable and the data will just wait in the kernels buffer until you read it. UDP is where you really want to read the entire message at once, because it doesn't make sense not to.

I believe it returns the size actually written to your buffer, not the message size.

well... ya. POOSIX is a fucking joke.

>>105651663
malloc isn't POSIX though - although you're right: GlobalAlloc, LocalAlloc, HeapAlloc, VirtualAlloc, VirtualAlloc2, NtAllocateVirtualMemory ... it's all hogwash.

oh no no no no ahahahahaha

ok, C is a fucking joke. same difference IMO.
C and POOSIX are basically bros.

>>105651680
You wanna know the best part? VirtualAlloc2 essentially calls NtAllocateVirtualMemoryEx, but not before checking if the extended parameters contain anything that might look like a page size hint. If one of them is, then VirtualAlloc2 fails instead.

tcp. okay cool

another question, when I send() asynchronously on a socket I run into an issue where if the socket has been created (non-blocking) but NOT connected, send seems to just crash my program instead of returning an error. I don't actually care if the send doesn't go through when there is no connection, but I want to see why it failed and respond to it. how do I do that?

>>105651758
SIGPIPE?

>>105651758

>>105651770

instead it crashes

>>105651767
oh, yeah this was the issue. setting MSG_NOSIGNAL on the send now works as I expected

>>105651745
So this is enough to make you seethe? The fact that this is optimal and faster than MMAP is all it takes for you to stop posting? Wow.

I've had the vague desire to implement fft for a while. It really seems like sort of a mystical algorithm, more complex than normal mathematical funtions.

unironically templates in C++ contain more symbols and are slightly less legible than templates through macros in C

C macros can fully be reimplemented using sed.
C++ templates cannot be fully reimplemented without spending billions of manhours writing a proper template parser in C++.

>>105660091
reimplementing all the macros that go into c is billions of manhours too

>>105662394
and to think, this will be implemented by major compilers as soon as 2052

>>105662206
It's certainly an oversight but I don't think this is a problem that happens all that often. The main goal of adding string_view was to have an efficient and standardized way of passing strings as references, because some people used const std::string& while others stuck to using const char *. It's not a drop-in replacement for either of those, because it's non-owning unlike a string and not null-terminated unlike a const char *. It has a pretty specific use-case. Also string_view works with all the iterator and range functions, I'm sure you could write a std::ranges one liner which does this.

>>105662852
sorry anon, but to someone who just wants to add two strings it all sounds like a bunch of cope

I think when C++26 drops, C++ will be truly dead. As much as I despise iToddlers, I think I will have to move to Swift, it's the only language which *feels* like C++ (aside from D).

Is there any advantage to passing state to a function as an object opposed to thread local global variables (also only used by this one function)? I will never want to use these functions from signal handlers.

>>105663305
C++ will be dead once the bald one keels over.

It's so comfy to not care about standards and just code.

Good compilers know how to avoid state switches on CPUs that aren't over 20 years old.

>>105663730
My compiler doesn't need to avoid state switches because I'm not using AVX to print 64bit integers, kill yourself.

>>105663738
Sounds like your compiler, your processor, and your life are trash. It also sounds like all of these are not my problem.

>>105665658
Depends, but usually yes.

Yes. Programming is 20% writing code and 80% debugging/testing. Maybe 30/70 if you're really good and experienced. Anybody who says/thinks otherwise makes shitty, broken software.

add(a, b) {
