When I'm reading from or writing to a network socket, I want to use a
struct to represent the structured data, but must use an unsigned char
buffer for the call to sendto() or recvfrom().
I have two questions:
1. Is it generally safe to "overlay" the structure on the buffer,
e.g.:
unsigned char buffer;

Hello! I am working on dividing a single C file into several files.
Now I encounter a problem about the global variables
and can not find a way to solve it.
All global variables and codes used to be in that single file, that
worked OK. But when I divdie that file into several ones, I
have many "invalid use of undefined type" errors.
The four files are main.c, main.h, readLP.h, and readLP.c.
In readLP.h

Hi,
I have two structs in a header file, and they reference each other,
causing a compile error. Is there a standard way to deal with this?
typedef struct {
...
RtAction *actions;
} RtWidget;

I'm writing a python program which reads input device events so it needs
to know sizeof(struct timeval). By using the struct module I should be
able to work out sizeof(long) from python, but I can't think of a way to
measure non-fundamental types without including a little bit of C,
which I'd rather avoid.
How safe would I be assuming that
sizeof(struct timeval) == 2 * sizeof(long)

Hi,
I am using a library (pcapy) that returns a timeval object T=
(seconds,microseconds) where microseconds is always < 1e6.
Is there a Python class that can handle timeval structs? Specifically,
I wish to subtract two T (defined above) objects, taking into account
the large values of T and T (esp T)?
At one point, I would have to step in, since T rolls back to zero
(after some time).

Hallo group members,
Do You know any conversion specification for this. I imagine:
struct timeval time;
printf("%T\n", time);
regards,

I'm trying to add the current time + a randomly generated time w/
millisecond precision, but the numbers aren't making sense.
If I add rand_time + now_time on my calculator, I get a different result
than what's in sched_time. Anyone see what I'm doing wrong?
These are my results ..
rand_time = 4958.128418
now_time = 1225033344.000000

With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
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...
