libft

My Library with own versions of C standard functions

Coded in

Most of the functions in this library are my own versions of existing standard functions.

The definition of the library functions can be found here.

The functions mentioned below are either not part of the libc or only in it in a different form:

• ft_substr:

  • Creates a substring out of string "s" from position "start" with a maximum lenght of "len".
  • Prototype: char *ft_substr(char const *s, unsigned int start, size_t len);

• ft_strjoin:

  • Creates a new string by adding the string "s2" to the end of "s1"
  • Prototype: char *ft_strjoin(char const *s1, char const *s2);

• ft_strtrim:

  • Removes all characters from a set of characters "set" from the start and end of a string "s" and returns the trimmed string.
  • Prototype: char *ft_strtrim(char const *s1, char const *set);

• ft_split:

  • Splits up a string "s" into substrings which are seperated by any amount of a character "c" and returns an array of the newly created strings.
  • Prototype: char **ft_split(char const *s, char c);

• ft_itoa:

  • Turns an integer "n" into a string and returns the string.
  • Prototype: char *ft_itoa(int n);

• ft_strmapi:

  • Applies the function "f" to each element of the string "s" and creating a new string it returns.
  • Prototype: char *ft_strmapi(char const *s, char (*f)(unsigned int, char));

• ft_striteri:

  • Applies the function "f" to each element of the string "s".
  • Prototype: void ft_striteri(char *s, void (f)(unsigned int, char));

• ft_putchar_fd:

  • Outputs a character "c" to the file descriptor "fd".
  • Prototype: void ft_putchar_fd(char c, int fd);

• ft_putstr_fd:

  • Outputs a string "s" to the file descriptor "fd".
  • Prototype: void ft_putstr_fd(char *s, int fd);

• ft_putendl_fd:

  • Outputs a string "s" followed by a newline to the file descriptor "fd".
  • Prototype: void ft_putendl_fd(char *s, int fd);

• ft_putnbr_fd:

  • Outputs an integer "n" to the file descriptor "fd"
  • Prototype: void ft_putnbr_fd(int n, int fd);
