Syntax

     char *index (string, character)           char *rindex (string, character)
     char *string, *character;                 char *string, *character;
     Description

     The  index  subroutine returns  a  pointer  to the  first
     occurrence of character in  string, while the rindex sub-
     routine returns a pointer to the last occurrence of char-
     acter in string.  Both subroutines return a value of 0 if
     the character does not occur in the string.

     These functions operate on null-terminated strings.  They
     do not check for overflow of any receiving string.

     See  "string"  for more  information  on  the strchr  and
     strrchr  subroutines, which  can be  used to  perform the
     same operations.
