INDEX(3)	       FreeBSD 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	char-
     acter, 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'').
