let's make a pool, when reflection stuff is gotta make it to the cpp standart

Dima

C++30?

Dima

I, personally, wouldn't like to use reflection stuff in c++, but there are some moments where it could just fit perfectly

C question: if i create a socket with the function socket(...) and i put the 2nd argument as SOCK_RAW, do i have to write the whole packet when i use the send() function or just the data?

Read the socket manual

Jussi

It is a raw packet

Jussi

So it is not capsuled eith a TCP/UDP header

BinaryByter

Read the socket manual

Dont worry, he wont, rtfm is "rude" according to him

Can someone explain this

The differences are only relevant on 16 bit [1] intel architectures and stopped being significant about 15 years ago.  In a nutshell virtual addresses on an Intel x86 chip have two components - a selector and an offset. The selector is an index into a table of base addresses [2] and the offset is added onto that base address. This was designed to let the processor access 20 bit (on a 8086/8, 186), 30 bit (286) or 46 bit (386 and later) virtual address spaces without needing registers that big. So... 'near' pointers don't have a selector - they have an implied selector. They can access 64k off the virtual address space on a 286 and earlier and 4Gb of the addresss space on a 386 or later. 'far' pointers have an explicit selector. However when you do pointer arithmetic on them the selector isn't modified. 'huge' pointers have an explicit selector. When you do pointer arithmetic on them though the selector can change. 'based' pointers... oh, you didn't ask about them. Basically ignore this. It's not worth the hassle to learn about unless you're an archaeologist. Cheers, Abhi [1] Okay, modern intel processors have all the old segmented guff still hanging about but the OS tends to set the selectors once and then forget about them. [2] In real mode there is no table of base addresses, the address is just the selector multipled by 16.

What kind of syntax is this? Declaration of something weird or many char pointer without any comma?

anyone online ?

can anyone help me finding why there is a runtime error in my code : https://paste.ubuntu.com/p/GFY3pJ6XjK/

Why have you written the programme so bad? Or is it a problem of the paste site?

Mat

I see a while loop, a for loop and an if statement on the same line

Mat

I don't see proper indentation, too

o my fucks that is terrible formatting

Mat

It isn't even clear what the programme should do

feggy

which site is this?

_̸̡͝͝This

hello !

_̸̡͝͝This

I need help with a simple thing

_̸̡͝͝This

Do you guys know of any tool to convert any string to a string with escaped characters that will equal the same in c ?

_̸̡͝͝This

for example, "ab % cdef \ ghij" to "ab \% cdef \\ ghij"

_̸̡͝͝This

I'm replacing the special characters myself, but I fear I might have missed a few of them...

Max

I'm replacing the special characters myself, but I fear I might have missed a few of them...

sed

Daniele°

You can use sed or perl

_̸̡͝͝This

oh, am, is sed a software ?

Daniele°

oh, am, is sed a software ?

Yes

Daniele°

Or you can use a bash script

_̸̡͝͝This

ooh, found it, thank you so much guys, i'll give it a try !

Daniele°

Language: perl Source: my $in='hello\ world %'; $in =~ s/([\\\%])/\\$1/; print $in; Result: hello\\ world %

Daniele°

Ops

Daniele°

Language: perl Source: my $in='hello\ world %'; $in =~ s/([\\\%])/\\$1/g; print $in; Result: hello\\ world \%

__getitem__

Does it matter ? I just needed to find why I am getting a runtime error . By the way , I have tried to perform a quick sort. For formatting thing , maybe its website problem.

I didn't understand anything from your code

do you know about quick sort ??
