INDEX(3)		    Library Functions Manual		      INDEX(3)

NAME
       index, rindex --	locate character in string

LIBRARY
       Standard	C Library (libc, -lc)

SYNOPSIS
       #include	<strings.h>

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

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

DESCRIPTION
       The  index()  and  rindex()  functions have been	deprecated in favor of
       strchr(3) and strrchr(3).

       The index() function locates the	first occurrence of c (converted to  a
       char) in	the string pointed to by s.  The terminating null character is
       considered  part	 of  the string; therefore if c	is `\0', the functions
       locate the terminating `\0'.

       The rindex() function is	identical to index(), except  it  locates  the
       last occurrence of c.

RETURN VALUES
       The  functions  index()	and  rindex()  return a	pointer	to the located
       character, or NULL if the character does	not appear in the string.

SEE ALSO
       memchr(3), strchr(3), strcspn(3),  strpbrk(3),  strrchr(3),  strsep(3),
       strspn(3), strstr(3), strtok(3)

HISTORY
       The  index()  and  rindex()  functions appeared in Version 6 AT&T UNIX.
       Their prototypes	existed	previously  in	<string.h>  before  they  were
       moved  to  <strings.h> for IEEE Std 1003.1-2001 ("POSIX.1") compliance.
       The functions are not specified by IEEE Std 1003.1-2008 ("POSIX.1").
