The rindex() function returns a pointer to the last occurrence of the character c in the string s. The terminating NULL character is considered to be a part of the strings. RETURN VALUE The index() and rindex() functions return a pointer to the matched character or NULL if the character is not found. CONFORMING TO 4.3BSD; marked as LEGACY in POSIX.1-2001. POSIX.1-2008 removes the specifications of index() and rindex(), recommending strchr(3) and str- rchr(3) instead.
