You cannot return an array with this way briefly .

i have a similar project to do involving UDP/TCP client/servers, but I spent the whole day building automatas for a compiler maniac. I'll get back to it 10h from now. But you should try your luck in the off-topic group, cause it's more about networks in general than C.

about "doing it correctly", I also messed up the first time I made a struct for NTP. Forgot 2 32-bit fields and my message kept being labeled as malformed, but I had no idea what was wrong haha... So yeah, It happens.

depends on your operating system, for windows you can take a look at the functions in wlanapi.h

int main()
{
int row=1,column=1;
int i;
do{
i=8;
do{
i--;
}while(i>=row);
column=1;
do{
printf("*");
printf(" ");
column++;
}while(column<=row);
printf("\n");

You can combine your inner two loops like this. Because notice, if you assign column before the first loop, the condition will always be true until you execute the body of the second loop.
do {
if (i >= row) {
--i;
} else {
printf("*");
printf(" ");
column++;
}
} while (column <= row);

NetworkManager is not part of the Linux kernel

Usually you can find such files in something like NetworkManager-dev or NetworkManager-devel
Nameful
Depends on your distribution

I installed dev let me try devel
Thanks 🙏🏻

Your distribution has either dev or devel. They're just two different conventions. If you have NetworkManager development files installed and they still can't be found you may need to specify NetworkManager's include path

const char* const* means pointer to const pointer to const character

https://cdecl.org/ is a pretty neat when you want to translate "C gibberish" to English
const char* const* x
translates to
declare x as pointer to const pointer to const char [1]
It's especially nice for more complex types such as char (*(*x[3])())[5]
"declare x as array 3 of pointer to function returning pointer to array 5 of char"

In the exercise I do we run echo %HOMEPATH% in cmd. For this purpose I wanted to do it like this
execve(“cmd”, “echo %HOMEPATH%”, NULL)
However, it seems to be incorrect as the second argument of the function limits to 1 character

That's (most likely) not a compile error, it does not prevent you from compiling.
