INDEX(3)		   Linux Programmer's Manual		      INDEX(3)

NAME
       index, rindex - locate character in string

SYNOPSIS
       #include <strings.h>

       char *index(const char *s, int c);

       char *rindex(const char *s, int c);

DESCRIPTION
       The  index()  function returns a pointer to the first occurrence of the
       character c in the string s.

       The rindex() function returns a pointer to the last occurrence  of  the
       character c in the string s.

       The  terminating	 null  byte  ('\0')  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.
