Creates a new string by concatenating s1 and s2.
Implementation
char *ft_strjoin(char const *s1, char const *s2)
{
size_t s1_len;
size_t s2_len;
char *join;
if (!s1 || !s2)
return (NULL);
s1_len = ft_strlen(s1);
s2_len = ft_strlen(s2);
join = (char *) malloc((s1_len + s2_len + 1) * sizeof(char));
if (!join)
return (NULL);
ft_memcpy(join, s1, s1_len);
ft_memcpy(join + s1_len, s2, s2_len + 1);
return (join);
}
