This has helped me with pointers and pointers arithmetic: http://www.eskimo.com/~scs/cclass/notes/sx10.html but i can't say i have mastered it yet, au contraire. You probably know that there is a...

Probably: ~/.local/share/Trash but i think i just read something which made me wonder (in other words: don't bet on it. I had to look it up myself and found it with: find . -name '*trash*' but...

Thanks. Your explanation and example makes it more clear (also thanks for pointing out it may not be best praxis, but for now i just try to understand the general idea).

I think you say that:...

Thanks so much, it seems clear now. I got another question about header files. Say i got checkr.h with: void check_argc(int, int); and the function in checkr.c: void check_argc(int argcount, int...

In the header file data.h i got:
const char ack_msg[] = "ack: received your msg\n";
In the code file server.c i got:
extern const char ack_msg[];
And else it is only used in a function call:

The C Programming language might be the bible, but it really is tough. Steve Summit has a good intro online: C Programming Notes (http://www.eskimo.com/~scs/cclass/notes/top.html) One level above...

In /etc/ssh/sshd_config
PermitRootLogin yes

But as a first quick test what the problem is you can simply run: ssh username@192.168.1.4

Anyway: I would disable root login (or keep it...

No, any additional info is very welcome. Both, pointers and the whole subject of memory, is very hard for me, in general.

Reading the FAQ about name[3] and *name i think this: I am quite sure that...

Ok, thanks a lot. You explained it very good. I ran into the problem a couple of times, but nothing i found really made it clear. I think i got it now.

Thanks, that makes it clear, especially all the comments. Main problem seems to have been to set the last element to NULL.

Divide sizeof the list by sizeof the first element i can remember. It...

When i want to use a list of strings
char *list[]; i never understand it well.

Here is an easy example. It took me long to figure it out, searching the web didn't help much:

#include...

Ok, thanks to both of you. And thanks to Corona668 for explaining it detailed.

Q.1: ok, thanks. y

Q.2: Inside of the function make_list() i declare a struct num_list tmp, but i don't allocate any memory. I allocate memory to the list, depending how much elements it will...

Thanks for your answer. I like the idea.
The following is how i implemented it, asking if that would be the way you proposed it:

#include <stdio.h>
#include <stdlib.h>


struct numlist {

Doing some training code with arrays i run into the following issue: If i ask the user how long the array is supposed to be, malloc it and then ask for the values inside the array and return the...

Debian releases - more or less - every two years a new stable.. After another time there will be no more security upgrades, so you can't run any stable version much longer than 3 years. I wouldn't...

If i use tightvncserver, ssh to the server then start it:
tightvncserver
and then connect with a client, i get the default gui (xfce in my case. I don't use a display manager, so i can't say...

Using the full path would work:

On another note the headers, on Gnu/Linux, are to be found at /usr/include. If you get an error you can do "man 3 printf" (if the function you use is printf) and the man page will tell you which...

I want to run a test for the gem mini_magick:
https://github.com/minimagick/minimagick

I got the directory lib, inside of which i got:
- mini_magick.rb
- mini_gmagick.rb

and inside of the...

Ok, thanks. I know in what direction to look.

I also found this and had some ideas (but like you say: it really can be hard to understand)

Using *retptr = p; in allocstr and &copystr in the...

Thanks. With
strcpy(linelist[index], line);
it works. But i think i had to add +1 to:
linelist[index] = malloc(len+1);

I still fail to understand why.
To me it looks like the while loop...

I am trying to get userinput from stdin and store the lines in an array.


If i do this:
using a char **list to store strings
allocate memory to it
#include <stdio.h>
#include <stdlib.h>

Thanks to both of you, i understand it much better now (now fully, but i am on my way). Yes, siva shankar, what you just explained is exactly what i did not see.

Ok, thanks. What i don't understand: Is there a difference between
0 * 0
1 * 0
...
10 * 0
in C ? Different: is the 10 arbitrary, or is it chosen for a reason?
