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.

       character or NULL if the character is not found.
