one last question lets say i have a function that is ued to print out an array , but i dont know what type of array it is until after runtime, could i use a void pointer as a parameter and cast the it later

Usually, you should pass a parameter that would tell the type

It's dangerous, because if the pointers aren't int, you will have a crash or undefined behaviour

That's c++, not c

You would be getting into c++ and templates

Is there some types except of char, int and double?

its either a character array or int array

I mean Can you say, that all element of array is one of those?

I was thinking passing a union

Do you have a graduation?

Huh

Do you have a graduation?

I don’t understand the context of the question

Curiosity

I am self taught

I'm studying computer science in Catania(Italy), I wanted to find an other person that study computer science

I am studying , it’s ok, I understand you , if you want a study buddy I am open

Okay

How far you in your degree? What languages have you worked with so far ?

I started in september😂 I graduated at school this year... We took C and C++ in these 2 month of course

Having fun yet lol

Where are you from?

NY

There are some Italians?

There are many

Daniel, are you american...? STOP TO EAT ALFREDO

I have eaten Alfredo lol

Alfredo doesn't exist in Italy lol

It’s not Italian ?

Yes, but in Italy it is not sold

It’s not Italian ?

Are Italians also to blame for spaghetti code?

Our "pasta" is actually thousands of years old, dating back to the early Etruscans (and even older italic poeple). During the time, we never shared anything with chinese cousine. (because they're too different, mainly)

Are Italians also to blame for spaghetti code?

It is a big deal actually and this cannot be solved without re-tuning of TCP stack on the machine. You must set TCP connection timeput for this. There is another solution actually, you can send fake data from time to time and hence mark the connection as alive internally, but if there is no such "PING packet" (actually it is not ping and not a packet at all) for a long time you can disconnect.

ok thank you, I will try right now

Hello guys i'm beginner. what's mean the code inside of the while block ? #include <linux/input.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #include <stdio.h> #include <unistd.h> int main(int argc, char **argv) { int fd; argc = 3; if(argc < 2) { printf("usage: %s <device>\n", argv[0]); return 1; } fd = open(argv[1], O_RDONLY); struct input_event ev; while (1) { read(fd, &ev, sizeof(struct input_event)); if(ev.type == 1) printf("key %i state %i\n", ev.code, ev.value); } }

It is a loop

It is a loop, continuously read data from the file (fd) you opened. Is it right?

Yes, more or less.

BTW, the handle leak problem I ran into yesterday was not caused by service... It is OS related issue. The issue cannot be reproduced on Win 10 1903 but can be reproduced on Win 10 IoT 2016.

I doubt

I can help you more in PM

Most probably, this is the problem of your service which can be traced and diagnosed on one OS, and cannot on another one.

To clarify if the issue was caused by my service, I create a console application an use the same methods to control the device. I also use devcon.exe from Windows SDK to test it and got the same result.

Simple C app and services have different lifetime circles so this is not an indicator.
