| ft_memalloc |
allocates (with malloc(3)) and returns a “fresh” memory area. The memory allocated is initialized to 0. If the allocation fails, the function returns NULL |
| ft_memdel |
takes as a parameter the address of a memory area that needs to be freed with free(3), then puts the pointer to NULL |
| ft_strnew |
allocates (with malloc(3)) and returns a “fresh” string ending with ’\0’. Each character of the string is initialized at ’\0’. If the allocation fails the function returns NULL |
| ft_strdel |
takes as a parameter the address of a string that need to be freed with free(3), then sets its pointer to NULL |
| ft_strclr |
sets every character of the string to the value ’\0’ |
| ft_striter |
applies the function f to each character of the string passed as argument. Each character is passed by address to f to be modified if necessary |
| ft_striteri |
applies the function f to each character of the string passed as argument, and passing its index as first argument. Each character is passed by address to f to be modified if necessary |
| ft_strmap |
applies the function f to each character of the string given as argument to create a “fresh” new string (with malloc(3)) resulting from the successive applications of f |
| ft_strmapi |
applies the function f to each character of the string passed as argument by giving its index as first argument to create a “fresh” new string (with malloc(3)) resulting from the successive applications of f |
| ft_strequ |
lexicographical comparison between s1 and s2. If the 2 strings are identical the function returns 1, or 0 otherwise. |
| ft_strnequ |
lexicographical comparison between s1 and s2 up to n characters or until a ’\0’ is reached. If the 2 strings are identical, the function returns 1, or 0 otherwise |
| ft_strsub |
allocates (with malloc(3)) and returns a “fresh” substring from the string given as argument. The substring begins at indexstart and is of size len. If start and len aren’t refering to a valid substring, the behavior is undefined. If the allocation fails, the function returns NULL |
| ft_strjoin |
allocates (with malloc(3)) and returns a “fresh” string ending with ’\0’, result of the concatenation of s1 and s2. If the allocation fails the function returns NULL |
| ft_strtrim |
allocates (with malloc(3)) and returns a copy of the string given as argument without whitespaces at the beginning or at the end of the string. Will be considered as whitespaces the following characters ’ ’, ’\n’ and ’\t’. If s has no whitespaces at the beginning or at the end, the function returns a copy of s. If the allocation fails the function returns NULL |
| ft_strsplit |
allocates (with malloc(3)) and returns an array of “fresh” strings (all ending with ’\0’, including the array itself) obtained by spliting s using the character c as a delimiter. If the allocation fails the function returns NULL. Example: ft_strsplit(" hello fellow students ", ’ ’) returns the array ["hello", "fellow", "students"] |
| ft_itoa |
allocate (with malloc(3)) and returns a “fresh” string ending with ’\0’ representing the integer n given as argument. Negative numbers must be supported. If the allocation fails, the function returns NULL |
| ft_putchar |
outputs the character c to the standard output |
| ft_putstr |
outputs the string s to the standard output |
| ft_putendl |
outputs the string s to the standard output followed by a ’\n’ |
| ft_putnbr |
outputs the integer n to the standard output |
| ft_putchar_fd |
outputs the char c to the file descriptor fd |
| ft_putstr_fd |
outputs the string s to the file descriptor fd |
| ft_putendl_fd |
outputs the string s to the file descriptor fd followed by a ’\n’ |
| ft_putnbr_fd |
outputs the integer n to the file descriptor fd |
