Creates a new list resulting from the successive applications of the function 'f'. The 'del' function is used to delete the content of a node if needed.	malloc, free	-
ft_lstnew	t_list *ft_lstnew(void *content);	Allocates (with malloc) and returns a new node. The member variable 'content' is initialized with the value of the parameter 'content'. The variable 'next' is initialized to NULL.	malloc	-
ft_lstsize	int ft_lstsize(t_list *lst);	Counts the number of nodes in a list.	-	-
ft_memchr	void *memchr(const void *s, int c, size_t n);	Searches the first n bytes of the memory area pointed to by s for the character c and returns a pointer to the first occurrence, or NULL if the character is not found.	-	-
ft_memcmp	int memcmp(const void *s1, const void *s2, size_t n);	Compares the first n bytes of the memory areas s1 and s2.	-	-
ft_memcpy	void *memcpy(void *dest, const void *src, size_t n);	Copies n bytes from the memory area src to the memory area dest.	-	-
ft_memmove	void *memmove(void *dest, const void *src, size_t n);	Copies n bytes from the memory area src to the memory area dest, even if they overlap.	-	-
ft_memset	void *memset(void *s, int c, size_t n);	Fills the first n bytes of the memory area pointed to by s with the constant byte c.	-	-
ft_putchar_fd	void ft_putchar_fd(char c, int fd);	Outputs the character 'c' to the given file descriptor.	write	-
ft_putendl_fd	void ft_putendl_fd(char *s, int fd);	Outputs the string 's' to the given file descriptor followed by a newline.	write	-
