The first project of the core curriculum - libft

Libft is the first project of the core curriculum of the 42 network. The project is about coding your own C library. It contains various general purpose functions.

Testernette for libft might be interisting for you if you're doing the core at the moment.

Part 1: libc functions

int     ft_isalpha(int c);
int     ft_isdigit(int c);
int     ft_isalnum(int c);
int     ft_isascii(int c);
int     ft_isprint(int c);
size_t  ft_strlen(const char *str);
void    *ft_memset(void *b, int c, size_t len);
void    ft_bzero(void *s, size_t n);
void    *ft_memcpy(void *dst, const void *src, size_t n);
void    *ft_memmove(void *dst, const void *src, size_t len);
size_t  ft_strlcpy(char *dst, const char *src, size_t dstsize);
size_t  ft_strlcat(char *dst, const char *src, size_t dstsize);
int     ft_toupper(int c);
int     ft_tolower(int c);
char    *ft_strchr(const char *s, int c);
char    *ft_strrchr(const char *s, int c);
int     ft_strncmp(const char *s1, const char *s2, size_t n);
void    *ft_memchr(const void *s, int c, size_t n);
int     ft_memcmp(const void *s1, const void *s2, size_t n);
char    *ft_strnstr(const char *s1, const char *s2, size_t len);
int     ft_atoi(const char *str);
void    *ft_calloc(size_t count, size_t size);
char    *ft_strdup(const char *src);

Part 2: additional functions

char    *ft_substr(const char *s, unsigned int start, size_t len);
char	*ft_strjoin(const char *s1, const char *s2);
char	*ft_strjoin.c
char	*ft_strtrim(const char *s1, const char *set);
char	**ft_split(const char *str, char c);
char	*ft_itoa(int n);
char	*ft_strmapi(const char *s, char (*f)(unsigned int, char));
void	ft_striteri(char *s, void (*f)(unsigned int, char *));
void	ft_putchar_fd(char c, int fd);
void	ft_putstr_fd(char *c, int fd);
void	ft_putendl_fd(char *c, int fd);
void	ft_putnbr_fd(int n, int fd);

Part 3: bonus functions

t_list  *ft_lstnew(void *content);
void    ft_lstadd_front(t_list **lst, t_list *new);
int     ft_lstsize(t_list *lst);
t_list  *ft_lstlast(t_list *lst);
void    ft_lstadd_back(t_list **lst, t_list *new);
