libft

The aim of this project is to code a C library regrouping usual functions that you'll be allowed to use in all your other projects.

Functions from <ctype.h> library

• [ft_isascii] - test for ASCII character.
• [ft_isalnum] - alphanumeric character test.
• [ft_isalpha] - alphabetic character test.
• [ft_isdigit] - decimal-digit character test.
• [ft_isprint]. - printing character test (space character inclusive).
• [ft_isspace] - white-space character test.
• [ft_tolower] - upper case to lower case letter conversion.
• [ft_toupper] - lower case to upper case letter conversion.

Functions from <stdlib.h> library

• [ft_atoi] - convert ASCII string to integer.
• [ft_calloc] - memory allocation.

Functions from <strings.h> library

• [ft_bzero] - write zeroes to a byte string.
• [ft_memset] - write a byte to a byte string.
• [ft_memchr] - locate byte in byte string.
• [ft_memcmp] - compare byte string.
• [ft_memmove] - copy byte string.
• [ft_memcpy] - copy memory area.
• [ft_memccpy] - copy string until character found.

Functions from <string.h> library

• [ft_strlen] - find length of string.
• [ft_strchr]. - locate character in string (first occurrence).
• [ft_strrchr]. - locate character in string (last occurence).
• [ft_strstr] * - locate a substring in a string.
• [ft_strnstr]. - locate a substring in a string (size-bounded).
• [ft_strcmp] * - compare strings.
• [ft_strncmp]. - compare strings (size-bounded).
• [ft_strnrcmp]. - reverse compare strings (size-bounded).
• [ft_strcpy] * - copy strings.
• [ft_strncpy]. - copy strings (size-bounded).
• [ft_strdup]. - save a copy of a string (with malloc).
• [ft_strndup]. - save a copy of a string (with malloc, size-bounded).
• [ft_strcat]. - concatenate strings (s2 into s1).
• [ft_strncat]. - concatenate strings (s2 into s1, size-bounded).
• [ft_strlcpy] - size-bounded string copying.
• [ft_strlcat] - size-bounded string concatenation.

Non-standard functions

• [ft_putchar] - output a character to stdout.
• [ft_putchar_fd] - output a character to given file.
• [ft_putstr] - output string to stdout.
• [ft_putstr_fd] - output string to given file.
• [ft_putendl] - output string to stdout with newline.
• [ft_putendl_fd] - output string to given file with newline.
• [ft_putnbr] * - output integer to stdout.
• [ft_putnbr_fd] - output integer to given file.
• [ft_itoa] - convert integer to ASCII string.
• [ft_substr] - extract substring from string.
• [ft_strtrim] - trim beginning and end of string with the specified characters.
• [ft_strjoin]. - concatenate two strings into a new string (with malloc).
• [ft_split] - split string, with specified character as delimiter, into an array of strings.
• [ft_strmapi] - create new string from modifying string with specified function.

Linked list functions

• [ft_lstnew] - create new list.
• [ft_lstsize] - count elements of a list.
• [ft_lstlast] - find last element of list.
• [ft_lstadd_back] - add new element at end of list.
• [ft_lstadd_front] - add new element at beginning of list.
• [ft_lstdelone] - delete element from list.
• [ft_lstclear] - delete sequence of elements of list from a starting point.
• [ft_lstiter] - apply function to content of all list's elements.
• [ft_lstmap] - apply function to content of all list's elements into new list.

Usage

make without bonus functions.

make bonus to compile with bonuses.

To use the library functions in your code, simply include its header:

#include "libft.h"

and, when compiling your code, add the required flags:

-lft -L path/to/libft.a -I path/to/libft.h
