My very first own library
This project consists of creating our own library with some of the most used functions in the C language and others that are exclusive to it. It will be very useful, since we will use it in our next projects in C.
| Name | Description |
|---|---|
| ft_isalpha | checks if it is an alphabetic character |
| ft_isdigit | checks if it is a decimal digit character |
| ft_isalnum | checks if it is an alphanumeric character |
| ft_isascii | checks if it is an ASCII character |
| ft_isprint | checks if it is a printable character |
| ft_strlen | returns the length of the string |
| ft_memset | fill the first len bytes of b with c |
| ft_bzero | erase n bytes of s with zeros |
| ft_memcpy | copy n bytes from src to dst (the memory areas must not overlap) |
| ft_memmove | copy len bytes from src to dst (The memory areas may overlap) |
| ft_strlcpy | copy dstsize - 1 characters from src to dst, ending with NULL |
| ft_strlcat | append the dstsize - ft_strlen(dst) - 1 characters from src to dst, ending with NULL |
| ft_toupper | convert lowercase letters to uppercase |
| ft_tolower | convert uppercase letters to lowercase |
| ft_strchr | returns a pointer to the first occurrence of the character c in the string s |
| ft_strrchr | returns a pointer to the last occurrence of the character c in the string s |
| ft_strncmp | compare the first n characters of strings s1 and s2 and return 0 if they are equal, otherwise return the difference between them |
| ft_memchr | return a pointer to the first instance of c in s until n bytes or NULL if the character does not occur in the given memory area |
| ft_memcmp | compare the first n characters of the memory areas s1 and s2 and return 0 if they are equal, otherwise return the difference between them |
| ft_strnstr | copies the string src, including the terminating null byte, to the buffer dest |
| ft_atoi | convert string str to int |
| ft_calloc | allocate unused space for an array of countelements each of whose size in bytes is size. The space shall be initialized to all bits 0 |
| ft_strdup | returns a pointer to a new string which is a duplicate of the string s |
| Name | Description |
|---|---|
| ft_substr | returns a substring from the string s. The substring begins at index start and is of maximum size len |
| ft_strjoin | returns a new string, which is the result of the concatenation of s1 and s2 |
| ft_strtrim | returns a copy of s1 with the characters specified in set removed from the beginning and the end of the string |
| ft_split | returns an array of strings obtained by splitting s using the character c as a delimiter. The array must end with a NULL pointer |
| ft_itoa | returns a string representing the integer received as an argument |
| ft_strmapi | Applies the function f to each character of the string s, and passing its index as first argument to create a new string resulting from successive applications of f |
| ft_striteri | Applies the function f on each character of the string passed as argument, passing its index as first argument. Each character is passed by address to f to be modified if necessary |
| ft_putchar_fd | Outputs the character c to the given file descriptor |
| ft_putstr_fd | Outputs the string s to the given file descriptor |
| ft_putendl_fd | Outputs the string s to the given file descriptor followed by a newline |
| ft_putnbr_fd | Outputs the integer n to the given file descriptor |
| Name | Description |
|---|---|
| ft_lstnew | returns a new node. The member variable content is initialized with the value of the parameter content. The variable next is initialized to NULL |
| ft_lstadd_front | Adds the node new at the beginning of the list |
| ft_lstsize | Counts the number of nodes in a list |
| ft_lstlast | Returns the last node of the list |
| ft_lstadd_back | Adds the node new at the end of the list |
| ft_lstdelone | Takes as a parameter a node and frees the memory of the node’s content using the function del given as a parameter and free the node. The memory of next must not be freed |
| ft_lstclear | Deletes and frees the given node and every successor of that node, using the function del and free. Finally, the pointer to the list must be set to NULL |
| ft_lstiter | Iterates the list lst and applies the function f on the content of each node |
| ft_lstmap | Iterates the list lst and applies the function f on the content of each node. Creates a new list resulting of the successive applications of the function f. The del function is used to delete the content of a node if needed |
1. Compiling the library
Inside the repository, run:
make2. Using it in your code
To use the library functions in your code, include the header:
#include "libft.h"and, when compiling your code, use the following flags:
-Lpath/to/libft.a -lft| Command | Description |
|---|---|
| make | compile the library |
| make bonus | compile the library with the bonus |
| make clean | delete all object files |
| make fclean | delete all object files and the library |
| make re | recompile the library |
