Functions List

1st part

• ft_memset

Set len bytes of b with char content of c.
void *ft_memset(void *b, int c, size_t len);

• ft_bzero

Set len bytes of s with '\0'.
void ft_bzero(void *s, size_t n);

• ft_memcpy

Copies n bytes from memory area src to memory area dest.
void *ft_memcpy(void *dst, const void *src, size_t n);

• ft_memccpy

Copies no more than n bytes from memory area src to memory area dest, stopping when the character c is found.
void *ft_memccpy(void *dst, const void *src, int c, size_t n);

• ft_memmove

Copies n bytes from memory area src to memory area dest.
void *ft_memmove(void *dst, const void *src, size_t n);

• ft_memchr

Scans the initial n bytes of the memory area pointed to by s for the first instance of c.
void *ft_memchr(const void *s, int c, size_t n);

• ft_memcmp

Compares the first n bytes (each interpreted as unsigned char) of the memory areas dst and src.
void *ft_memcpy(void *dst, const void *src, size_t n);

• ft_strlen

Calculates the length of the string pointed to by s, excluding the terminating null byte '\0'.
int ft_strlen(const char *s);

• ft_strdup

Returns a pointer to a new string which is a duplicate of the string s.
char *ft_strdup(const char *s);

• ft_calloc

Allocates memory for an array of nmemb elements of size bytes each and returns a pointer to the allocated memory. The memory is set to zero.
void *ft_calloc(size_t nmemb, size_t size);

• ft_strlcat

Appends the NUL-terminated string src to the end of dst. It will append at most size - strlen(dst) - 1 bytes, NUL-terminating the result.
size_t ft_strlcat(char *dst, const char *src, size_t destsize);

• ft_strchr

Returns a pointer to the first occurrence of the character c in the string s. char *ft_strchr(const char *s, int c);

• ft_strrchr

Returns a pointer to the last occurrence of the character c in the string s. char *ft_strrchr(const char *s, int c);

• ft_strnstr

Locates the first occurrence of the null-terminated string little in the string big, where not more than len characters are searched. char *ft_strnstr(const char *s1, const char *s2, size_t len);

• ft_strncmp

Compares the two strings s1 and s2 and return the difference between chars. int ft_strncmp(const char *s1, const char *s2, size_t n);

• ft_atoi

Converts the initial portion of the string pointed to by nptr to int. int ft_atoi(const char *str);

• ft_isalpha

int ft_isalpha(int c);

• ft_isdigit

int ft_isdigit(int c);

• ft_isalnum

int ft_isalnum(int c);

• ft_isascii

int ft_isascii(int c);

• ft_isprint

int ft_isprint(int c);

• ft_toupper

int ft_toupper(int c);

• ft_tolower

int ft_tolower(int c);

2nd part

• ft_substr

char *ft_substr(char const *s, unsigned int start, size_t len);

• ft_strjoin

char *ft_strjoin(char const *s1, char const *s2);

• ft_strtrim

char *ft_strtrim(char const *s1, char const *set);

• ft_split

char **ft_split(char const *s, char c);

• ft_itoa

char *ft_itoa(int n);

• ft_strmapi

char *ft_strmapi(char const *s, char (*f)(unsigned int, char));

• ft_putchar_fd

void ft_putchar_fd(char c, int fd);

• ft_putstr_fd

void ft_putstr_fd(char *s, int fd);

• ft_putendl_fd

void ft_putendl_fd(char *s, int fd);

• ft_putnbr_fd

void ft_putnbr_fd(int nbr, int fd);
