# Asm-library

### _Reproduction of some C standard functions used for working with C-style strings and lists in assembler (NASM)_

## Description:

Basic part of the lib contains the following functions: 

```c 

size_t  ft_strlen(const char *str);

char   *ft_strdup(const char *str);

char   *ft_strcpy(char *dst, const char *src);

ssize_t ft_read(int fd, void *buffer, size_t length);

int     ft_strcmp(const char *str1, const char *str2);

ssize_t ft_write(int fd, const void *buffer, size_t length);

```

Additional part uses the following struct:

```c

typedef struct        s_list

{

    void              *data;

    struct s_list     *next;

}                     t_list;

```

* Field `data` can store any type 

* Field `next` refers to the next element of the list 

It also contain these functions to work with the list:

```c

int   ft_atoi_base(char *str, char *base);

int   ft_list_size(t_list *begin_list);

void  ft_list_push_front(t_list **begin_list, void *data);

void  ft_list_sort(t_list **begin_list, int (*cmp)());

void  ft_list_remove_if(t_list **begin_list, void *data, int (*cmp)(), void (*free_ctl)(void *));

```

## Creation:

Use **`make`** or **`make -C `** to compile basic part of a lib. 

If you want create library with additional part, you should use **`make bonus`**

## Using examles:

Compiling with .c/.o/.s files: 

* `gcc test.c -L  -lasm -I `

* `gcc test.o /libasm.a` 

## Run test:

Use **`make run`** or **`make runb`** to compile library with test main function. 

To run test type **`./a.out`** and pass them 2 or 3 args:

* `./a.out "hello"` will test all basic functions except strcmp 

* `./a.out "hello" "world"` will test all basic functions including strcmp
