NAME
     iinnddeexx, rriinnddeexx - locate character in string

LLIIBBRRAARRYY
     Standard C Library (libc, -lc)

SYNOPSIS
     ##iinncclluuddee <>

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

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

DESCRIPTION
     The iinnddeexx() 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 rriinnddeexx() function is identical to iinnddeexx(), except it locates the last
     occurrence of c.

RETURN VALUES
     The functions iinnddeexx() and rriinnddeexx() return a pointer to the located char-
     acter, or NULL if the character does not appear in the string.
