rindex —
#include <strings.h>
char *
  
  rindex(const
    char *s, int
  c);
rindex() function locates the last character
  matching c (converted to a char) in
  the nul-terminated string s.
This function is obsolete. The equivalent function strrchr(3) should be used instead.
NULL is returned. If c is
  ‘\0’, rindex()
  locates the terminating ‘\0’.
rindex() function conforms to IEEE
  Std 1003.1-2001 (“POSIX.1”). The IEEE
  Std 1003.1-2004 (“POSIX.1”) revision marked it as legacy
  and recommended the use of
  strrchr(3) instead. The
  IEEE Std 1003.1-2008 (“POSIX.1”)
  revision removed rindex() from the specification.
rindex() function appeared in
  Version 6 AT&T UNIX.
