For example: 1. Traditional socket recv is synchronous lying 2. Call recv in lua and wait in sync 3.lua will exit lua vm and hand over control to c language 4.c language call WSARecv delivers asynchronous read request 5. When WSARecv requests complete data filling into lua 6. Re-enter LUA VM 7.recv Return

Assign a lua ctx to each connection

WSARecv is an IOCP that posts a recv request that returns asynchronously.

Thankyou guys for suggesting me book C primer plus from Stephan Parta. It's great book, really well explained

It depends If ICPC member knows how to write good code, he/she will, if it's needed

Guys I need a help with formation of ships in sea battle. I would be glad to discuss my problem in direct.

Mar!o

So whats the problem?

Dima

constinit const static auto i = 5;

What a time to be alive

Roxifλsz 🇱🇹

constinit const static auto i = 5;

Jesus Christ how horrifying

Dima

Lol

Ибраги́м

Jesus Christ how horrifying

Very very very

Ибраги́м

Imagine if we apply attributes

Francisco

Well, the static is not necessary

Ибраги́м

Well, the static is not necessary

Are u sure ?

Francisco

A constinit variable is like a mutable constexpr variable

Ибраги́м

So, u have no evidence...

Ибраги́м

constinit - specifies that a variable must have static initialization, i.e. zero initialization and constant initialization, otherwise the program is ill-formed. https://en.cppreference.com/w/cpp/language/constinit

Francisco

Sorry, I was mistaken with other thing hahaha

Sorry, I was mistaken with other thing hahaha

OK, I thought as much. It was wierd.

Francisco

A constinit variable is like a mutable constexpr variable

But this remains true

Ибраги́м

Jay don't do it

Ибраги́м

Don't, it will get u banned

Anonymous

Ok

Ибраги́м

But this remains true

True 💯 When the const is removed in the above snippet, u can reassign to i. i =10;

Ибраги́м

[[gnu::a_very_uselless_attribute]] constinit const static auto i = 5; The fun never stops.

Francisco

What I wanted to say is that constinit const = constexpr

Jussi

wtf [[gnu::a_very_uselless_attribute]]?

Ибраги́м

wtf [[gnu::a_very_uselless_attribute]]?

It's a uselless GNU attribute.

Jussi

i know of maybe_unused

Ибраги́м

What I wanted to say is that constinit const = constexpr

Ah, too much drinking sire

Jussi

why is it typo'd?

Ибраги́м

why is it typo'd?

Attributes that means nothing to compiler or language gets ignored

Jussi

lol

Ибраги́м

[[gnu::a_very_uselless_attribute]] constinit const static auto i = 5; The fun never stops.

That's why u can do sth like this and still get away with it, it's stealing goods worth <= 900$ in Carlifornia.

Hey

Mar!o

How is it possible to get a fancy rank?

Dima

How is it possible to get a fancy rank?

What?

Mar!o

Well next to your name - Code warrior. Or what is this?

yoav

i created a function "mulstr" that need to multiplay the string many times as wanted by the argument here is the function: char* mulstr(char* str, int multi){ char* multipled; for(int i = 2; i <= multi; i++){ strcat(multipled, str); } return multipled; } and i got into a error segmention fault and i do not know why

Surge.rs

Prolly because you are using strcat which is accessing memory its not allowed to access and resulting in segfault

so what do i need to do to get this function to work

For one the char* doesnt have a defined size and they are also read only. Try using dynamic memory allocation with malloc so you have better ability to manipulate the output

C or C++?

Francisco

I have a question regarding synchronization. I want to make yet another productor-consumer program (wrapped in a class), but I think I keep getting a deadlock and can't really find where I'm wrong (there surely is some lack of understanding): https://godbolt.org/z/9QzUj-

Surge.rs

C or C++?

Looks like C as not using std::string
