LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <strings.h>

       [[deprecated]] char *index(const char *s, int c);
       [[deprecated]] char *rindex(const char *s, int c);

DESCRIPTION

       index() is identical to strchr(3).

       rindex() is identical to strrchr(3).

       Use strchr(3) and strrchr(3) instead of these functions.

STANDARDS

       4.3BSD;  marked  as  LEGACY  in  POSIX.1-2001.  POSIX.1-2008 removes the specifications of
       index() and rindex(), recommending strchr(3) and strrchr(3) instead.
