Oh, C++ people, if I'm using calloc, do I need to free up the memory when I'm done with it?

Ronan Forman

@SaintWacko I only know C, but I think so.

two bugs

@SaintWacko I don't remember for calloc, but for malloc you absolutely do.

Ronan Forman

From the looks of it yes.

two bugs

Unless you like memory leaks!

Ronan Forman

@twobugs Apparently the difference is that calloc initialise the list to 0.

SaintWacko

7:04 PM

Thanks! I'm not used to working with memory like this

Ronan Forman

@SaintWacko I know, it sucks.

I think most compilers will unallocate memory at the very end of the process, but I'm not 100% sure.

SaintWacko

Ahahaha

input = "@0" + input + "@E";
	cout << input << '\n';
	char * contents;
	contents = (char*)calloc(sizeof(input), 1);

I couldn't figure out why the function kept saying that there was no text being sent to the api

Just realized that while I set the length of contents, I never actually put "input" in it

Rapitor

so how broken is Win10 anyway, is it "safe" to upgrade to yet?

badp

Whatever happened to smart pointers?

Learning C++ through one thousand cuts, by @SaintWacko

SaintWacko

smart pointers?

@badp And yeah, that sounds about right

Now I'm trying to figure out how to put input in contents

James

7:16 PM

@SaintWacko reference counted pointers to know when they can Actually be deleted or not.

Rapitor

smart pointers don't leak

James

@Rapitor Yeah they do

SaintWacko

Ahh

Rapitor

well.. yeah, but not as much.

Q: What is a smart pointer and when should I use one?

What is a smart pointer and when should I use one?

James

7:16 PM

If you dont clear up the references they leak just like any other pointer

badp

I'm not entirely sure why you're using C++ tbqh

James

They are more to make sure that you dont delete something something Else in the code is still referencing

badp

if you were using Python you'd have been done by now :P

James

@badp Uh.. I am pretty sure python is an acronym for wanting to stab your eyes out.

user15026

James

7:17 PM

I just cant figure out the words to make it work :)

badp

@James You must first learn the zen of Python to unlock its secret acronym.

@AshleyNunn actually I have to reset the router our ISP gave us. I "bricked" it somehow while trying to set it properly to use 192.168.0.0/24 instead of 192.168.1.0/24 and now it won't respond to any request

James

@Unionhawk I am James and I approve of this message.

SaintWacko

@badp Because I don't think the API works with Python

user15026

@badp Okay, yeah, but you know what you are doing

badp

@James I've also worked professionally on Python and I have been quite happy with it, despite the codebase showed some age.

@AshleyNunn Bricking a router doesn't sound like knowing what I'm doing

also there is no reset button

James

7:20 PM

@badp I shall leave that work to you :D

badp

so I have no idea how to bring it back to factory status.

Unionhawk

@badp RIP

badp

@James Very gladly

SaintWacko

So does anyone have a preferred way to load a string into a char pointer?

James

@SaintWacko load from where?

Kevin van der Velden

7:20 PM

.c_str() is not an option?

Unionhawk

Scream and ask why am I using C++?

I've not used C++ in like a year >_>

James

Co-Worker and I had a nice discussion about the language Rust recently

badp

I just look at how much time poor @SaintWacko is wasting doing the most basic of shit done and cry

James

I use all 3 C's on a nearly daily basis

@SaintWacko strncpy?

James

@SaintWacko memcpy

Unionhawk

@badp It isn't cobol

James

@KevinvanderVelden @SaintWacko or that

SaintWacko

@KevinvanderVelden .c_str() has to be a const char*, and that isn't compatible with LPSTR

Kevin van der Velden

Ah

James

7:23 PM

@SaintWacko strncpy(dest, string.c_str(), len) should work

Yuuki

@Unionhawk No, it's COBOL.

Unionhawk

@Yuuki Nope.

That's the 4th C that shall not be named

It's not cobol, it's COBOL.

Q: Using /effect on people with a certain amount of points on a scoreboard

So I am trying to make a double jump for my server and i want to give people the jump boost effect when their score on the objective "Jumping?" is 1. I tried /effect @a[score_Jumping?=1] 8 3 10 but that didn't work. Please help!

minecraft minecraft-commands

Unionhawk

@Lazers2.0 oh god why did you name your objective with a question mark

oh god

Yuuki

7:28 PM

@Lazers2.0 So he's implementing double jump by tying it to a score?

Unionhawk

And that won't work since you can't perform a second jump input even if you suddenly have jump boost in the air

James

@Yuuki Yeah unfortunately.. Common Object Business Oriented Language...

@murgatroid99 Hmm... then I need to either convert my Python code to JavaScript/jQuery or figure out how to make JavaScript/jQuery call a Python script.

murgatroid99

@Yuuki What browser-based operation could you possibly be doing that's easier with Python than JS?

Yuuki

@murgatroid99 Not easier or anything, I already have it in Python.

I wrote it awhile ago while building the chatbot.

SaintWacko

Okay, here's what I'm doing

Q: PS4 external hard drive for game updates?

So I have a PS4 with the 500 gb hard drive and all from 2014 when they were being first released, and as of late I have had to delete updates for games (NOT dlc's / add-ons ) so I could update games or download a new one because I am lacking space. I have a good 7 games that I really like to play...

ps4

SaintWacko

It sounds like it's something to do with the null terminator, but I'm not sure exactly what

murgatroid99

7:35 PM

@SaintWacko Strings take up n+1 bytes, where n is the length

Unionhawk

I feel like sizeof(contents) may be doing something stupid but I have no clue

murgatroid99

@Unionhawk this, too

Unionhawk

It might be an off by one though

SaintWacko

@murgatroid99 So the string is null terminated, but the char* is not

So should I have it like this instead?

strncpy_s(contents, sizeof(contents), input.c_str(), sizeof(input) - 1);

murgatroid99

@SaintWacko Sorry, C mode. The char* is null-terminate. I don't know how the string is implemented

Powerlord

7:36 PM

@SaintWacko Should that second sizeof be input->size instead?

SaintWacko

Oh, okay

murgatroid99

Pause for a moment

What types are contents and input?

SaintWacko

@Powerlord I have no idea

Yuuki

SaintWacko

input is std::string, contents is a char*

Powerlord

7:37 PM

@SaintWacko Yes, and std::string has a size element on it.

Yuuki

And this is why if you have porn saved on your hard drive, you don't put it in the My Pictures folder. You utter moron.

murgatroid99

@SaintWacko OK, sizeof(contents) is 8, and sizeof(input) is however big a string object is

They're not useful values

SaintWacko

@Powerlord Oh, and I can access it with that ->size?

@murgatroid99 Why is it 8?

Powerlord

er... actually, it's probably .size since std::string may not be a pointer.

Unionhawk

I've never fully understood -> versus .

murgatroid99

7:38 PM

@SaintWacko Because that's how many bytes are in a char *

Powerlord

I'm not a C programmer by trade.

murgatroid99

@SaintWacko How did you create contents?

SaintWacko

@murgatroid99 So when I used calloc, it's not actually setting any size to the char*, it's just allocating memory at that location?

Powerlord

@Unionhawk -> is for pointers, . is for non-pointers.

SaintWacko

char * contents;
contents = (char*)calloc(sizeof(input), 1);

murgatroid99

7:39 PM

Oh God

Powerlord

I'm not sure why you'd want to calloc anyway when you can just char contents[100] to get a 100 character string.

murgatroid99

@Powerlord I thought the point was that we don't know how long input can be

SaintWacko

@murgatroid99 Yes

murgatroid99

@SaintWacko Why aren't you just using input.c_str()?

SaintWacko

@murgatroid99 Because then it has to be a const char*

And the api function doesn't accept that

Powerlord

7:41 PM

Makes me wonder what the api function does.

badp

@Unionhawk syntactic sugar

murgatroid99

@SaintWacko Do a const_cast

badp

Do a barrel_roll

SaintWacko

@Powerlord Sometimes it takes what you give it and puts something there

Powerlord

As a general rule, in C and languages close to it, when you're just consuming a string and not altering it, you want to accept a const char *

Mainly because you can pass a char * or a const char * to something that wants a const char *, but not the other way around.

murgatroid99

7:43 PM

@Powerlord Oh, right, that's a good point. Maybe there's a reason it's not supposed to be const

@Powerlord I think that's different between C++ and C

SaintWacko

@Powerlord That's the problem, it is being altered

@murgatroid99 What do you mean?

murgatroid99

@SaintWacko OK, you are passing a string that already contains data, and it's getting modified?

SaintWacko

@murgatroid99 In this case it is not getting modified

Powerlord

I don't use C a lot, but I use languages derived from Pawn, which is based on C and has some of C's... limitations.

SaintWacko

But sometimes the string passed to the api does get modified

murgatroid99

7:44 PM

But you just said it's being altered

Wipqozn

@AshleyNunn I'm having Sushi for supper

SaintWacko

@murgatroid99 In some cases it is. There's a single api function for all api calls

It's kinda weird

murgatroid99

@SaintWacko And they alter the input string instead of having a separate output buffer?

Wipqozn

@Yuuki I am fine with saturday not happening because I can't make it Saturday and I don't want anyone else to experience happiness.

Powerlord

...and one lib that's pretty common (it's called TF2Items) takes a char[] when it should take a const char[]

SaintWacko

7:45 PM

hllapi(&HFunc, contents, &HLen, &HRc);

@murgatroid99 Right

murgatroid99

@SaintWacko that doesn't mean anything

What are the types of those arguments?

SaintWacko

@murgatroid99 hllapi(LPINT, LPSTR, LPINT, LPINT)

It's from IBM

murgatroid99

OK, wow. Anyway, yeah, it does look like you want to use that contents buffer

Powerlord

...so, you ARE using that hllapi.

SaintWacko

@murgatroid99 Yeah :) I've been through a lot of what you're going through right now already :P

Never mind, I was just misreading the typedef

SaintWacko

Oh, okay

Jason Berkan

7:49 PM

Sweet. MLP Season 5 is now on Netflix.

SaintWacko

So it looks like the way I'm doing it now is the best way to do it?

murgatroid99

@SaintWacko So, yeah, you want contents = calloc(input.size + 1, 1)

Wipqozn

@JasonBerkan That reminds me, I ned to watch season 6.

Oh wait, no season 5

SaintWacko

@murgatroid99 Okay

Wipqozn

huh, I'm so behind.

I'm such a monster.

SaintWacko

7:50 PM

Then do I need to change the strncpy_s, too?

Powerlord

@Wipqozn Season 6 won't out for a LONG time.

murgatroid99

@SaintWacko And then use that value for both numbers in the strncpy_s

Jason Berkan

@Wipqozn I only watch it on Netflix, so I'm just as far behind as you are. Monster.

Powerlord

Heck, they're not showing the second half of season 5 until fall.

Unionhawk

@Yuuki you're fired

Jason Berkan

@Wipqozn Not really a fan, but I had to watch it given how often it is discussed. I honestly only really like the episodes with Discord.

Wipqozn

@JasonBerkan John De lancie is pretty rad

Jason Berkan

I find most episodes are generic kids programming. Especially the Cutie Mark Crusaders. I hate them.

SaintWacko

7:53 PM

@murgatroid99 I forgot, it's making me cast it

Wipqozn

@JasonBerkan Cutie Mark Crusaders are basically the worst

SaintWacko

contents = (char*)calloc(input.size + 1, 1);

Powerlord

Incidentally, I may have been lying about the DayMare Sun thing.

You won't know until you finish watching them!

SaintWacko

And... hmmm

It's complaining that input.size is an unsigned int, and so I can't add to it?

murgatroid99

@SaintWacko Try casting the 1 to a size_t

And, you might want to just stick string.size + 1 in a size_t variable so you don't have to do that 3 times

Jason Berkan

7:56 PM

@Powerlord I assumed you were. Well, actually, at first I was confused about whether that was something that had happened in an episode I watched, but that my memory is going due to my old age.

Powerlord

@JasonBerkan ...you got me, DayMare Sun is fake. Nightmare Moon may make an appearance in season 5, though. Or I could be lying. Again.

murgatroid99

SaintWacko

@murgatroid99 It still doesn't like that

error C2296: '+' : illegal, left operand has type 'unsigned int (__thiscall std::basic_string<char,std::char_traits<char>,std::allocator<char>>::* )(void) throw() const'

murgatroid99

@SaintWacko input.size()

And then you shouldn't need the size_t cast

SaintWacko

@murgatroid99 I tried that too

Still the same error

@SaintWacko What's the error message?

OK, what's the context of the message?

Or, rather, what's the documentation for the API you're calling?

SaintWacko

The error is on this line, I think strncpy_s(contents, size, input.c_str(), size);

@murgatroid99 www-01.ibm.com/support/knowledgecenter/SSEQ5Y_5.9.0/…

The File is tcsncpy_s.inl

murgatroid99

@SaintWacko Try replacing the second size with input.size()

SaintWacko

@murgatroid99 still getting the debug assertion failed

murgatroid99

8:08 PM

It looks like strncpy_s automatically NULL terminates, and expects the last parameter (the number of characters to copy) to be smaller than the size of the output buffer

SaintWacko

Hmmm

murgatroid99

@SaintWacko And size is input.size() + 1?

Jason Berkan

This is a wonderful reminder of why using a language with a sane String class makes programming so much more enjoyable.

murgatroid99

@JasonBerkan The problem here is converting between C++ strings and C character arrays

Unionhawk

hahahahaha right

8:11 PM

Windows, instead, just plops all the characters in and doesn't terminate the string if the destination is smaller than the source.

murgatroid99

@Powerlord The only strncpy_s documentation I could find was MSDN, and I don't see that mentioned anywhere

@Powerlord Anyway, in this case the destination is larger than the source

@SaintWacko Are you sure that the assertion failure is coming from strncpy_s?

Jason Berkan

Isn't the (in)correct solution to put in a cast to shut up the compiler?

SaintWacko

@murgatroid99 I guess not 100%, but it comes during the first call of the Send function, and the file it says it occurs in is a cpy function

Powerlord

@murgatroid99 My bad, I was thinking snprintf.

(which is defective on Windows)

SaintWacko

It occurs somewhere in here

void Send(string input)
{
	cout << "Sending: \"" << input << "\"\n";
	size_t size = input.size() + 1;
	input = "@0" + input + "@E";
	char * contents;

murgatroid99

It tells you how big a type is, which is important for doing things like allocating memory to hold an item of that type

SaintWacko

It's not crashing on anything now, but there are a few weird characters at the end of the char *

murgatroid99

Wait, why do you have a sizeof in that code up there?

That was why there were weird characters
