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:

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:

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:

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 <path_to_libdir> 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 <path_to_lib> -lasm -I <path_to_lib>
  

• gcc test.o <path_to_lib>/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
