Function name:
ft_substr
Prototype:
char *ft_substr(char const *s, unsigned int start, size_t len);
Parameters
s: The string from which to create the substring.
start: The start index of the substring in the string ’s’.
len: The maximum length of the substring.
Return value:
The substring.
NULL if the allocation fails.
External functs.
malloc
Description:
Allocates (with malloc(3)) and returns a substring from the string ’s’.
The substring begins at index ’start’ and is of maximum size ’len’

SYNOPSIS
#include <ctype.h>
int
tolower(int c);
#include <ctype.h>
#include <xlocale.h>
int
tolower_l(int c, locale_t loc);
DESCRIPTION
The tolower() function converts an upper-case letter to the corresponding
lower-case letter. The argument must be representable as an unsigned char
or the value of EOF.
Although the tolower() function uses the current locale, the tolower_l()
function may be passed a locale directly. See xlocale(3) for more informa-
tion.
RETURN VALUES
If the argument is an upper-case letter, the tolower() function returns
the corresponding lower-case letter if there is one; otherwise, the argu-
ment is returned unchanged.
