This project aims to code a C library regrouping usual functions that can be used in all other 42 projects.
The content of this repository is subject to constant change as new general functions developed during other projects are added here.
| Command | Usage |
|---|---|
make |
creates .o files for each function as well as the main library file, libft.a |
make clean |
removes the .o files used to create the library |
make fclean |
removes the .o & .a files used to create the library |
make re |
removes all .o & .a files then remakes them |

| ft_strdup.c | allocates sufficient memory for a copy a string copies and returns a pointer to it |
| ft_striteri.c | applies the function f to each character of the string passed as argument |
| ft_strjoin.c | allocates and returns a new string (concatenation of two strings) |
| ft_strjoin_free.c | same as ft_strjoin(), but it frees the old string |
| ft_strlcat.c | appends two strings |
| ft_strlcpy.c | size-bounded string copying |
| ft_strlen.c | counts the numbers of characters preceding the terminating NUL-character of a string |
| ft_strmapi.c | applies a function to each character of a string, creating a new string with the modifications |
| ft_strncmp.c | compares (lexicographically) up to n characters of two strings |
| ft_strnstr.c | locates the first occurrence of the null-terminated substring in the a string, where not more than n characters are searched |
| ft_strrchr.c | locate last occurrence of character in string |
| ft_strtrim.c | allocates and returns a copy of a string with the characters specified in ’set’ removed from the beginning and the end of the string |
