what?

I m thibking to switch to a newer linux distro

Is it better than debian ubuntu

KDE neon is just "Ubuntu LTS+KDE desktop environment". LTS distros are for stability, and rolling distros are for new softwares. You decide

I need a distro with best looking and near stable with good package management system

guys, i need a suggest: how i allocate dynamic memory shared between more process? i try to explain better: i have a process that generate (with fork) 20 child process. i have created two struct: // data of the single child process struct single_data { unsigned long content; pid_t writer; }; // type of data structure struct shared_data { // index where next write will happen unsigned long cur_idx; //* vector that contains all data to be written: //* - vec[i].content = i //* - vec[i].writer = PID of process who wrote i in vec[i].content struct single_data vec[NUM_PROC*NUM_ITER]; }; but now the size of this struct is defined in the header by num_proc and num_iter. how i can converter them to dynamic allocation?

you have fast modification for that

Hey... is there a anyone who can help me with a small java script issue... I'm new to this....😳

If you know any of right group for my question plz suggest me. Because i only have this group...

@letstalkprogramming

good morning group. I did a simple program, but this one with erroneous results. If possible, someone could look at my code for me. Please

No, nobody will fix your code.

Why if a declare a shared memory in main.c when I do fork() and execve the child (child.c), the child don't see the shared memory? The variables are declared in header.h but if I declare them in main.c it does not work anyway

Because fork creates a whole new process, and memory of all processes is seperated. What you're looking for is a thread

No, if I put everything in the same time (main.c) it works. It stops working only when I split into 3 files (main.c child.c header.h)

Show us your code then

is a bit 'confused, I hope you understand the problem

If someone fixes your code, you'll never learn :D

Nothing special, wait for 1024.

fork() generates a new process as the child-process of the original one. For the virtual memory space, Linux handles it by COW technology. This optimization roots on the fact that, if exec*() another program is called in the child-process imediately after fork(), eager copy the virtual space is useless. In your case, you fock() from gestore and then execl() the program figlioA, which matches the design of fork-COW. Hence, in the child-process, the whole virtual space of its father-process is dropped and thus invisible. If you put everything in the same source file, and keep running the same program in the child-process, the virtual space inherited from its father-process will then COW-ed, and hence elements are still valid and visible. However, for this situation, your shared_data is shared between the two process only for the name —- modifying it in one process triggers Linux to copy it in physical memory and to reattach the map between physical memory frame and virtual memory page, and thus the modification is invisible in another process.
