index(3)                   Library Functions Manual                   index(3)

NAME
       index, rindex - locate character in string

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 str‐
       rchr(3) instead.
