Just bind, accept, read/write

I dont need to know how kernel buffers data, i dont need to know which syscalls are called when i read data from a socket

Jussi

I dont need to know how the network layer works in kernel, nor how the driver works

With enough knowledge, C can easily replace python/perl/bash etc

hmm , well , it can , but yk .. segfaults and etc thats isn't how python work

but the point here

Anonymous

hmm , well , it can , but yk .. segfaults and etc thats isn't how python work

so don't write programs that segfault

Anonymous

simple

Jussi

You clearly are a newbie in C

Anonymous

but the point here

why you would even make such a thing

Jussi

What thing?

Jussi

Simple socket server?

Anonymous

Simple socket server?

yes

Jussi

Well

Anonymous

why you would even do it in C

Jussi

For example for very simple IPC (inter process communication)

Jussi

Inside the same PC

Jussi

So you can transfer data between programs

Anonymous

Message Queues?

Anonymous

That's better in C

Jussi

But if the other program is not written in C

Jussi

The client I mean

Anonymous

You mean for IPC or MQ?

Jussi

Either

Jussi

Is there a mq library for python?

Jussi

For example

Anonymous

so don't write programs that segfault

other thing , its not portable nor have enough apis/libs to replace a langauge like python , and not sure about perl , didn't use it before

Anonymous

Ah, well MQ just does message passing so it's just a case of having a socket and a matching API

Jussi

And IIRC MQs have some synchro problems if the amount of data is big

Anonymous

depends which one you use

Jussi

Was it only for sysV?

Anonymous

Apache's ActiveMQ is pretty good, as is RabbitMQ

Anonymous

but I use ZeroMQ which is a bit less capable but much lighter

Jussi

Aah you are talking something else than POSIX/unix

Anonymous

wait

Anonymous

is MQs like the dbus ?

Jussi

MessageQueue

Anonymous

Aah you are talking something else than POSIX/unix

yeah, it's a means of communicating between servers in distributed systems

Jussi

I thought you meant posix/sysV message queue

Anonymous

Oh, no lol

Anonymous

And IIRC MQs have some synchro problems if the amount of data is big

isn't it found to solve this exact problem ?

Jussi

What exact problem? Maybe in some newer apis, and I might even remember wrong

Anonymous

What exact problem? Maybe in some newer apis, and I might even remember wrong

to store the messages in the queue ? to make the overloaded data hold in the queue in a wait state ?

Jussi

Yeah but I just remembered that there was some limit, and after that you couldn't be sure about the actual order of the messages anymore

Jussi

I'm not 100% sure about it now, I can check it once I get home

Anonymous

Yeah but I just remembered that there was some limit, and after that you couldn't be sure about the actual order of the messages anymore

well , if it was preprogrammed DS its possible

Anonymous

but in general terms if you would program in C

Anonymous

you can make your own MQ types

lol

lol this is a masterpiece

What is int* n

°_°

?

Dima

a pointer?

Dima

int* n and int *n are the same

Dima

I prefer int* n, looks good

Dima

Mat

I prefer int* n, looks good

Same. Looks better for me 'cause "n" is the variable, not *n, and int* the type.

Anonymous

I prefer int* n, looks good

int * n is bae , lel

°_°

Char* n= abcd; cout<<n;

°_°

What's the output?

Igor🇺🇦

What's abcd?

Dima

'abcd'

Dima

fits 32

Dima

wait

Dima

I thought its int

Dima

lol

Onur

Same. Looks better for me 'cause "n" is the variable, not *n, and int* the type.

the problem is that makes misunderstanding if you define more than one variable in one line such as: ìnt* a, b; Here a is pointer but b is just an integer. However, I still choose int* a.

the problem is that makes misunderstanding if you define more than one variable in one line such as: ìnt* a, b; Here a is pointer but b is just an integer. However, I still choose int* a.

so, you write int* a, * b;?

Onur

It is possible but I think its more ambigious than int *a, *b; But still usually there is no need to define two pointer at the same place.

Evgenii

there is algorithm which literally called "two pointer algorithm"

°_°

Can someone help me with this?

°_°

Char* n= abcd; cout<<n;

.

Igor🇺🇦

.

Without defining what's abcd it will not compile. Any way you can try for yourself here: https://ideone.com/dJ4zhI

°_°

Ah

°_°

I was assuming it like a string

°_°

In a char type

°_°

Someone tells me that the output is "a"

°_°

But I can't find why
