Libft | School 42 project // C library | Learning library

I am trying to create a static library using a shell script.

For creating the library I used following script:

So, right now my Makefile looks like this

I have function named ft_split(char const *s, char c) that is supposed to take strings and delimiter char c and divide s into bunch of smaller strings.

It is 3rd or 4th day I am trying to solve it and my approach:

1. Calculates no. of characters in the string including 1 delimiter at the time (if space is delimiter so if there are 2 or more spaces in a row than it counts one space and not more. Why? That space is a memory for adding '\0' at the end of each splitted string)

2. It finds size (k) of characters between delimiters -> malloc memory -> copy from string to malloc -> copy from malloc to malloc ->start over.

But well... function shows segmentation fault. Debugger shows that after allocating "big" memory it does not go inside while loop, but straight to big[y][z] = small[z] after what it exits the function.

Any tips appreciated.

** Hello :)

So I have this task to write a program that will convert int to arg using malloc and well it all works fine, gdb shows no errors, but it is not printing any output in this form. If i delete itoa_buffer[i] = '\0'; than sometimes it shows output sometimes not. I do not know what is wrong here, seems fine.

I do not know where to ask for help as I like to follow my logic and find errors here instead of copying solutions from the internet. I willl appreciate some tips, its probably some small thing Id do not know and wont let me go further.**

I need something like strlen but the string is filled with only null-terminators "\0\0\0\0\0\0\0" and I need to fill it with another character up until (not including) the last \0 like so "FFFFFF\0". Is there a way to calculate the size without errors?

I had to implement bzero for a school project called "libft". Then I was tasked with implementing strcpy and I saw in the man pages that dest needs to be large enough to receive the copy of src so I want to account for a situation where bzero was used on dest and strcpy doesn't allow me to pass the size of dest as a parameter. I was just wondering (out of curiosity) how I would know how big dest is because I know that strcpy does not account for this. There is a warning in the man page "Beware of buffer overruns! (See BUGS.)".

I realise now that this might be impossible in C.
