Hi all,
This isn't minimal code, but at least it gives the idea reasonably well
- and yes, I'm a newb :(
The point of me giving this code is that all three vars look to my eye
as though they're being treated in exactly the same way, so that I end
up confused about why the address-of-char doesn't get returned the way
the other address-of-types do.

Hi,
I've read several questions and often the answer was
'C knows nothing about .'
So if C knows that little as some people say, what are the benefits, I
mean do other languages know more or is it a benefit that C knows nearly
nothing (what I can think about is that C is the largest common divisor
defined on most available platforms)?

Hi all,
I was wondering how does address alignment to x byte boundary is done.
For example, if I say "adjust the requested size to be on a 4-byte
boundary" or for that matter 8 byte boundary. How is this
adjustment/alignment done?
I goolged around alot and wans't able to find how is it done, all it
said was what is byte alignment and byte padding.

Hi,
I'm writing an application in which a client (C#/WinForms) and server
(C#/service) interact with one another. The client establishes a "session"
with the server but for scalability reasons there is not a one to one map
between a session and a physical TCP connection. A client may disconnect the
TCP connection if it is idle for more than 60 seconds... yet a conceptual
"session" may last for days at a time.
It's necessary that the...

What is the effective behaviour if you cast a memory address? I have
come across code where memory address 0 is cast to a 'struct foo'
type. What does this amount to? Does address 0 now point to address 0
of the 'struct foo'?

I am trying to write a program that will continuously sniff eth0 for a specific UDP packet thats being sent to a specific destination IP, alter the data of the packet, and finally transmit it to the destination. My script compiles fine and runs fine until it finds the specific packet and tries to alter the payload of the data. Hopefully someone can give me some insight on why it might be doing this...

Hello all,
I am newbie in Networking. I have just started studying Networking.
I have a doubt
" Do every router/gateway determines physical address of other router or systems prior to the delivery of packets? If it is so then what is the need of IP address?"
Please help me to understand core networking concepts.
Thanx and regards,

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
