NAME

       index, rindex, lnblnk, len - tell about character objects

SYNOPSIS

       (intrinsic) function index (string, substr)
       character*(*) string, substr

       integer function rindex (string, substr)
       character*(*) string, substr

       function lnblnk (string)
       character*(*) string

       (intrinsic) function len (string)
       character*(*) string

DESCRIPTION

       Index  (rindex) returns the index of the first (last) occurrence of the substring substr in string, or zero if it does not occur.  Index is
       an f77 intrinsic function; rindex is a library routine.

       Lnblnk returns the index of the last non-blank character in string.  This is useful since all f77 character objects are fixed length, blank
       padded.	Intrinsic function len returns the size of the character object argument.

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 character 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.
